One of my favorite innovations of recent years is Youtube. It's amazing what's on that site. For more than 20 years, I was looking for a clean copy of Wayne King's 1931 hit Dream a Little Dream of Me, or at least one that sounded better than my beat-up 78, but had no luck. On Youtube, I found that one, as well as versions by other artists.
Yes, You Tube is an excellent source of the classic music. That Wayne King version of “Dream a Little Dream of Me” is a peach! I love it!
