While we're with P.J. here's a track from a 1969 album The Three Week Hero backed by all four members of the young Led Zep, the first time they all recorded together in a studio in Autumn 1968. He was so impressed by them he offered them a gig as his backing band. Sadly, he hasn't seen them again since.
As a post-script, curiouser and curiouser I found that this song too is available at my local jukebox!
