There is a song running through my head and I can't place what play it came from or what musical... the only thing I can remember is it is sung by a man that is lamenting his past, the only lines I can remember are:
At seventeen... blah blah blah...
At twenty one... blah blah.. I came undone at 21.
It's a mournful tune but a good showtune, what is this song?!
