Refresh. I can't remember the song title, unfortunately - I heard him perform it at The Red Lion FC in Birmingham earlier this year and I haven't been able to find it on any of his recordings (although I know a lot of his stuff from the 70s isn't available anymore.) I can't remember any specific lines from it and as far as I'm aware no-one else has recorded it! If there are any needle-in-haystack specialists out there I'd be dead grateful for the lyrics!
