Lou and Peter Berriman have a great new humorous song called "Older Than Everybody" that is very cute and really much more possitive than it sounds. Another that comes to mind is "The Dancing Boilerman" (Writer Charlie King... he was from CT, USA about 25 years ago). It's especially approprate for a dancer as it is about a factory worker who enjoys retirement because he and his wife take up "dancin' at the YMCA". That's square dancing...and it's laced with dance calls that could probably be changed to any style.
Some of the earler entries are downright depressing. I don't know about everybody elase, but I'm looking forward to those years!
