I enjoyed what I heard of his solo work. But,,, I have a question. Was he in the Fleetwood Mac band that opened for Zappa on tour? If so, that band was awful. Everyone listened to two or three songs, and then headed out to the lobby and hallways. But,,, again, I enjoyed his solo work, and I hope he wasn’t in that Fleetwood band.
IIRC Welch was in the band from like 1970 to 74. he wasn’t an original member. I don’t know when they opened for Zappa.
