John McEuen produced Steve Martin's new CD. McEuen taught Martin to play the banjo when they worked together at Disneyland (Knott's Berry Farm?? I don't remember which now.) in the early 1960's. Steve Martin used to open for McEuen's band the Nitty Gritty Dirt Band in the early '70s. The album "Dirt, Silver and Gold" from 1976 has a older picture of Steve with long hair and a beard, wearing "the arrow" from the "Wild and Crazy Guy" era.
Earl Scruggs' is a living legend. Most people only know him from the theme to the "Beverly Hillbilly's". I have been watching the BH's recently with my 6yr old daughter. I didn't realize how often Flatt and Scruggs were on the program. Both as guest starts or doing cameos in the closing credits. If it wasn't for Earl Scruggs, the original "Will the Circle be Unbroken" album by the Nitty Gritty Dirt Band would not have been the seminal album it was.
