I've just stepped out of the time machine for this -heard a version of the song done by a bloke with a guitar about 25 years ago in a garden in Railway St, Splott. Some people there said he'd written it, but Gordon Wells told me that it was more of a ... homage? I've only just found it again as most of a recording on youtube, after many years looking for it. I can't find your lyric post, John?
