John Cale making an in-store appearance at the old Twist and Shout location in Denver. The best vocalist in The Velvet Underground, arguably.
I saw Cale play a solo show at a club called The Broadway back in the late '80s. He performed an abbreviated set and encore. "The spirit is willing, but the flesh is weak," he said before ending his gig.
Luckily, the flesh is healthier these days. And the spirit, like the music, shines like a black diamond.
