Well, after reading that on the base drum I took a closer look at the band and wouldn't you know it, there was Frank Thomas playing his heart out on Piano. It was a quick look, but it was pretty obvious it was Frank. These are the "Hidden Mickey's" of movies that just let us know that this is never just a 9-5 job for the artists that draw these great animated movies.
Go out and see The Princess and the Frog it was great. I can't wait to see it again.
