This next item also appears over at Saturday Morning Archives, since this is a clip from American Bandstand.
Jefferson Airplane performs "White Rabbit" & "Somebody to Love" on Bandstand, with Dick Clark interviewing the band in between. Dedicated to the memory of guitarist Paul Kantner, who passed away at 74.
Nearly 30 years later, actor-comedian Jim Carrey recorded an a capella solo version of "Somebody to Love" for his movie, "The Cable Guy". Have to put that up some time.
