Oh, yeah! In fact, I'm glad that somebody finally started a thread about Charlie.
I caught a BBD show at Ferris College in Big Rapids, Michigan, in 1978. It was their tour for the Drastic Plastic
album. Loved the material, loved the show!
Not only did Charlie play really interesting, quirky, eccentric bass parts that were ultra-tight, but he also combined musicianship with a sort of simultaneous "choreography", which consisted of a series of little dance moves that he performed back and forth across the front of the stage while playing the bass, i.e. jumps, straddles, heel clicks, strides, poses, etc. etc. - all timed to synchronize perfectly with the rhythm of the music.
Most impressive. And most entertaining as well.
Methinks that Charlie really, really enjoyed performing. And it showed.
