Another song that Alton claimed to write (with Smith) is Beautiful Brown Eyes, which was a number #1 song in 1949- which means: big money involved. Although I believe they arranged it, I'm pretty sure he didn't write it.
Alton wrote alot of great songs but it's a pity he took credit for some of them that he didn't write. If you look at the list above (Arthur Smith Trio) their are some songs which are clearly PD. Teh common practice at that time was the first one to record a song "wrote it."
What do you think?
