Johnny Cash "A Boy Named Sue"
Paul McCartney "Put It There"
Angie "Peppermint Lump"
Madonna "Oh Father" (or "Papa Don't Preach")
Queen "Father to Son"
Wayne Newton "Daddy Don't You walk so Fast"
personally I'm glad we avoided Mr Chapin, tho' I know that's a Father's Day staple to many. And amazingly we also skipped "Papa Was a Rolling Stone"
