Since we are talking about all of this old music, I thought it might be nice to point out a couple or three good sites for listening to some of the great old popular songs and tunes from various eras. So here are some places I think are worth visiting. Marybeth's has two sections dedicated to instrumentals. I started to post many of the songs from there but thought you might just want to ferret them out yourselves. I always drift off into my dream world every time I visit there.
Oh, and just in case my HTML skills are a little lacking, I included the URL's beneath each attempt!
