When I said they were all a copy of the DT, I meant of course just that song (right down to the initials at the end!), not the entire DT (though if they have one, they might have them all). I think I googled:
"Goodbye song" "Here's my song" lyrics
I was hoping I might turn up an author and that might lead to a sound clip, alas to no avail.
Perhaps Dick or Susan know who the contributor JK is and can get some more information.
