edgar, I love My Buddy. Bobby did a great job with that one. For the longest time, I thought that it had to do with the buddy system in the fox holes during WWII.
I did find this:
The music was written by Walter Donaldson, the lyrics by Gus Kahn. The song was published in 1922. It is universally believed this song was written about a World War I soldier who lost his friend in battle.
Dys, that was the most beautiful classical piece that I have heard in a while. Don't know Joaquin Rodriguez and can't find much about him, either.
Well, folks, here's an answer to Bobby's Buddy.
