From its original treatment, the story of Purple Rain had always revolved around three characters: Prince (a.k.a. “the Kid”), Morris, and Vanity (later replaced by Apollonia). Yet, in the early stages of production, Prince and director Albert Magnoli envisioned a broader depiction of the Minneapolis music scene, with subplots for the various supporting players. There was even talk of the accompanying album including tracks from associated artists, along the lines of the later Graffiti Bridge soundtrack. In the end, of course, this ensemble version of Purple Rain was not to be; the final album and film are both unambiguously Prince’s show. But Magnoli’s draft screenplay made plenty of time for one supporting player in particular: “Jill,” the First Avenue waitress played by Prince’s real-life backing singer and paramour, Jill Jones.
On August 1, 1983, Albert Magnoli arrived in Minneapolis to finish his revised screenplay for Purple Rain. He spent his first week in town interviewing the prospective cast members, including Prince’s band, the Time, and Vanity 6, to mine their real-life relationships for dramatic potential. As he explained to sessionographer Duane Tudahl, “My research was for me to sit down and say, ‘Okay, I have a scene I’m developing between you, Wendy, Lisa, and Prince, and you’re very angry at him. And you’re in the dressing room and you’re about to go on and you want to know if he hear[d] your music. Give me what you feel like?’ And they start, ‘Oh well, yeah that happens all the time!’ So all their shit comes up because they’ve been in that with him” (Tudahl 2018 117).
The director supplemented his research by sitting in on band rehearsals and attending the August 3 First Avenue performance where the film’s title song received its debut. Mostly, though, he wrote: spending his days in a motel room drafting in longhand, “from seven to seven… with a ruler and pencil, on paper. Then a secretary would come in and type everything up from that day in script form” (Light 2014 91). By the end of the month, when Magnoli flew back to Los Angeles to finish editing James Foley’s Reckless, his first draft was complete.
Of the six new, original songs Prince debuted at First Avenue on August 3, 1983, three–“I Would Die 4 U,” “Baby I’m a Star,” and “Purple Rain”–were sourced directly from the concert recording for his upcoming album and film. A fourth, “Let’s Go Crazy,” was re-recorded in short order at the Warehouse rehearsal space; while a fifth, “Electric Intercourse,” never saw official release in Prince’s lifetime. But it was the sixth–a cerebral punk-funk workout called “Computer Blue”–that would occupy Prince for the rest of the month, with weeks of overdubs spanning both Minnesota and Los Angeles.
The genesis of “Computer Blue” was in the intensive rehearsals at the Warehouse in summer of 1983. As keyboardist Dr. Fink recalls in the Purple Rain expanded edition liner notes, “We were jamming at rehearsal one day and I started to play a synthesizer bass part along with the groove. It happened to catch Prince’s ear, so he had our sound man record the jam.” The band continued to work on the song and, according to drummer Bobby Z, had it “just about fully rehearsed” when Prince threw another element into the works: a lyrical guitar solo based on a melody by his father, John L. Nelson, later to be dubbed “Father’s Song” (Revolution 20).
With Albert Magnoli on board as director, preparations for Prince’s film debut finally began in earnest. The artist’s new rehearsal space on Highway 7 in St. Louis Park, Minnesota became the epicenter for a “flurry of activity from morning ’til night,” recalled Brenda Bennett of side project Vanity 6 (Bellaire 2015). Along with a stage setup and recording console, “the Warehouse” also included a small wardrobe department for Vaughn Terry and Louis Wells: costume designers, best known for their work with Earth, Wind & Fire, who had joined the Prince camp during the 1999 tour and would be instrumental in crafting his iconic Purple Rain-era look.
Soon, Terry and Wells would be joined by another familiar face: tour manager Alan Leeds, whose capable handling of the inter- and intra-band tensions during the latter months of the 1999 tour led to his being rehired to help coordinate the film’s production. “I got a call from [manager Steve] Fargnoli sometime in July, offering me the gig to come to Minneapolis,” Leeds told journalist Alan Light. “And I said, ‘Well, what’s the gig? Are you going back on the road?’ ‘Not right away. We’re going to make a movie first.’ I go, ‘Okay, you need me to come there because you’re making a movie? First of all, I don’t believe you’re making a movie. Second, why do you need me to make a movie? I don’t make movies.’ He said, ‘We got three bands: we got Prince and his guys that you tour managed, we got Morris [Day] and the Time, we got Vanity 6. They’re all in the movie. Everybody’s taking acting lessons, everybody’s taking dance lessons, and everybody’s rehearsing new music. We need an off-road road manager to coordinate all this stuff.’ ‘Okay, Steven–you’re really making a movie? Get the fuck outta here!’” (Light 2014 82-83).
Leeds wasn’t the only one surprised by the sudden increase in scale. As keyboardist Lisa Coleman recalled, “For the longest time, we would talk about [the film] like, ‘We’re gonna make the best cult movie, it’s gonna be cool, we’re just gonna put it out there and see who responds to it.’ Then Al Magnoli came and actually kind of connected with Prince, and Al was the one who was like, ‘If we’re gonna make a movie, why don’t we make it a hit movie? It seems like we’ve got all the parts here. Let’s not just make some artsy movie, just for fun’” (Light 2014 91).
In aiming for a “hit,” however, Prince faced the inevitable temptation to sand away some of his rougher edges. Guitarist Wendy Melvoin, who had been a fan before she joined Prince’s band, recalled being disappointed by the new material at rehearsal: “The songs weren’t as funky to me,” she told Light. “They were pop songs; they were definitely watered down.” Coleman remembered Prince himself poking fun at his newfound populist tendencies: “He would imitate an old granny, like, ‘You could make Granny dance to this one,’ but then I think he was just like, ‘We’re leaning it too far to the granny; we still need danger’” (Light 2014 77).
