Just watching a PBS program called Moments to Remember and I realize that I know many many songs.  I'm always telling my daughters that I don't know the names or words to the current music but ohhhh ... just put on that music from the 50's, 60's..yes, even some of the 40's...and I can sing along with the best of them.  Well, what I mean is that I know the words, not that I sing them well.  I've also discovered tonight how hard it is to sing along when you're crying.
