I Know Times Are Changing
The band challenged the audience with a setlist where half the songs were brand-new, premiering more than 45 minutes of material that no one had ever heard. After almost an hour, Wendy began the penultimate song of the set. A few slow chords, heavily chorused, served to introduce the audience to a new, unfamiliar ballad. For the first ten seconds of the song, the only sound heard was Wendy’s guitar ringing out.
Ten months later, on June 25th 1984, the world got its first listen to those broad, mournful chords as the title track of a brand new album: Purple Rain.
A few weeks later, Wendy and Lisa were back in their home state of California, joining their boss Prince, who was having a very auspicious visit to Los Angeles. On August 20, less than three weeks after the charity gig, Prince had been asked to come onstage at a James Brown concert, at the behest of Michael Jackson, who had been singing with Brown onstage. It was the only time the three men would occupy a stage together, and seemed an almost-explicit anointing of Prince by both the funk legend and the man who was then enjoying the height of Thriller’s success.
