Hmm, that’s odd, Gerry. He certainly used to have one with all of his song lyrics on it, so there could be no debate about which were the correct versions of his songs! It came with advice to contact Larrikin Music if you wanted to record any of them commercially, but otherwise he was happy for others to just enjoy singing his songs.
I’ve done a search and can’t find it now, though I have used it on a number of occasions in the past.
