Thank you very much.....this has really helped more than you know.

I realize there are many answers to my original question, but you have
given me a great deal of info.

I will continue checking your answers. I am trying to compile a list
for a radio program. I am adding songs like "Good Night Irene", etc...some songs from the 40's, 50's.....many many from the 60's (just
because there were sooooooo many great ones then (I am 52).

Thank you again for your help, I really do appreciate it.
