Greg Reeves is an American bass guitarist. He is best known for playing bass on Crosby, Stills, Nash & Young’s Déjà Vu (1970). (More from Wikipedia)
Crosby, Stills & Nash wasn’t really as new as that quote seemed to indicate; the band had released their debut album Crosby, Stills & Nash in May 1969, three months before Woodstock, and the recording sessions began in June 1968. I had always thought that Neil Young was the man peeking out of the door on the back cover of Crosby, Stills & Nash, but it was actually their drummer Dallas Taylor. Young did join up for their next album, Déjà Vu; the album was released under the name Crosby, Stills, Nash & Young (with drummer Dallas Taylor and bassist Greg Reeves also credited on the cover in smaller print).
