I thought of Roy when I saw a link to a Hall & Oates story on CNN today, especially this quote:
Both men were raised in the Philadelphia, Pennsylvania, area and attended Temple University in the late '60s, but didn't formally meet until their respective bands were set to play an R&B teen dance in 1967. Oates: "We were waiting backstage to go on and a big gang fight broke out and we went down the service elevator and we left. And as we were going down we kind of met."
Gang fight? Gunfire and clubs and dog chains? Hall: "Typical Philadelphia scene. We didn't even blink an eye."
