+1 Tony! Yep - Of course, I have the PSR Tutorial "10,000 Songs" USB drive and I already know a ton of the oldies. A simple 20-30 seconds and you can have a style loaded. Or for many songs, you can just select a style that is appropriate and cover it.

For requests I don't feel I'm ready to try, I always say "If you come back the next time I am here, I will have the song ready just for you". Have done that with several customers and some of the folks now come every time I am there just for "their song". Got a few nice tips out of the effort too!
