A Son of the Rock

This is by the Magic Lanterns, of whose existence I only learned when I looked the song up on You Tube.
They do seem to have had some impressive members, though, who went on to greater things.

However, the (actually quite good) version of this song that I remembered – and the reason I was searching for it – was by Chicory Tip.

Yes, that Chicory Tip. (Wiki article here.)
