This one is by request for Gobshyte. Dunno too much about Dr. Know. In fact, I never been more than a casual fan. Courtship of Eddie's Father kid singing (the name escapes me right now sorry) was the singer for the first year or so. They did play up here some, but seemed to stay down in LA more. They sure embraced the thrash metal thing in the mid to late '80's for what it is worth. Their bassist and singer moved to SJ in or around 2000 or so. Nice guys, did some drinking with them..they were fun to hang out with!
