His name might not be familiar to everyone, but he was quite a talent. He was a member of the Kingston Trio through most of the 60s (he joined in 1961 when they were major stars), wrote "Daydream Believer" for the Monkees, and then recorded a bunch of solo albums, scoring one big hit in the late 70s with "Gold" (which featured members of Fleetwood Mac). His own version of "Daydream Believer", with some different lyrics, is a favorite of mine.
I recall I wanted to see him perform at Maxwell's in Hoboken, NJ years back; I can't remember whether the show was cancelled or something came up for me or what, but I never did get to see him. Wish I had.
Doctor J, in terms of 50, I wasn't talking about his street cred through his lyrics or songs... I was talking about his reputation as someone who isn't afraid to do what (he percieves) needs to be done.
