Is it possible to do a cover version of your own song?
Grace Slick wrote "Somebody to Love" (and "White Rabbit") while she was a member of The Great Society, a local San Francisco band. After The Great Society broke up, Signe Anderson, the lead singer of another local San Francisco band Jefferson Airplane, left that band due to the birth of her child. The Airplane asked Grace Slick if she would like to join the band and replace Signe. And the rest, as they say, is history.
Everyone knows the Airplane's version of "Somebody to Love" and "White Rabbit," so here's a "reverse cover"... the original version of "Somebody to Love" recorded by Grace Slick and The Great Society before she joined Jefferson Airplane and they had a big hit with the song...
