From Wikipedia, the free encyclopedia.  Gonna Fly Now , also known as  Theme from Rocky , is the theme song from the movie Rocky, composed by Bill Conti with lyrics by Carol Connors and Ayn Robbins, and performed by DeEtta Little (the sister of actor Cleavon Little) and Nelson Pigford.
Ron Grainer wrote the tune itself, but it was an electronics whizz called Delia Derbyshire who turned it into the eerie sounds we now recognise as the theme tune.
