Any autobiographical song where the singer whines ('whinges' for you Aussies) about a dead relationship and life in general.
About your dead pet story Bill, last week Tom Lewis was here (shanty singer extraodinaire) and at a pub party afterwards with twenty or so moderately lubricated Portland shanty singing folk, he started a song that had the response line "I say". Well, it didn't come back to him loud enough the first time, and so he asked, "You can all sing that, can't you? Let me hear it."
That *LOOK* went around the room, just like you said, Bill, and for the rest of evening, any quarter note rest in any of his songs had an "I say!" in it. Often several people in unison or harmony.
He was heard to mumble as he left the pub, "I guess I should have left well enough alone." I think he'll be back, though.
Blessings,
