Former band member Chris Hayes later remarked, "I don't know why 'Heart & Soul' sounds so good. Usually we have to re-do all the guitar parts – this time it worked out the first time. I had a Marshall amp in a tiny room, played my Les Paul and it was great!"[3]
Music video
The music video featured Lewis looking for, and leaving with, a woman in a dance club, with Lewis concert footage spliced in. Portions of the video are filmed at Potrero Hill, a neighborhood in San Francisco.[4] Lewis liked Potrero Hill because it "looked very San Francisco".[4] Actress Signy Coleman plays the woman Lewis is chasing after in the dance club.[5] Coleman also appears in the music video for "I Want a New Drug".[6]
It was very funny. My agent said, "They're looking for punk rockers so I want you to put some of that spray stuff in your hair and put on torn fishnet stockings." I said, "Lynn, I'm not doing that. I don't look anything like a punk rocker." I said I'll put on high heels but that's about the extent of it. I went to the audition and there were 50 of the most hardcore punk rockers I've ever seen. I turned around to leave and the director popped his head out of the room they were casting in and said, "Hey, miniskirt, where are you going?" He pulled me in and said they were also looking for a girl who's the opposite and stands out in the crowd of these unusual characters. I was asked to pretend to flirt with a guy across the room, which I like to believe I had a little experience with at that point.
They put on "Heart and Soul" (first time I heard it) and said, "Dance to it." I had been a dancer for many years, starting ballet at seven. At 13 I was on full scholarship for the San Francisco School of Ballet, but quit at 16 because I saw a destructive lifestyle—diet pills, cigarettes. I mean no disrespect to anyone doing it, but the world of dance can be cutthroat. But the discipline I learned in dancing has carried through the rest of my life. By the time I'd gotten home from the "Heart and Soul" audition, I'd already gotten the call that I got the video. No one knew at the time how MTV was going to change the fabric of the music industry.
