A couple that the late Iain Mackintosh used to sing:
Waltzing around in the Nude, and
(Can't remember the title) a song that started at death, then worked back through old age, pension age, middle age, young married, pre-married, teenage years, boyhood, babyhood and finally back in mother's womb!

Ian McCalman has one about being reasonably accepting of reaching sixty.

And, Jim Carroll, is the "All Used Up" song way up the thread, Feb 01, the one you want? Very powerful song. The late John Wright also sang it.
