Tiny Moore is the man to listen to for Western Swing, and also Johnny Gimble. Tiny played in the Bob Wills band and can be heard to great effect on the "Tiffany Transcriptions" L/Ps set. The problem with swing is the need for a guitarist playing backup "Sock" chords. I don't think it works for solo mandolin. Tiny Moore released a book and tape on his method many years ago, which is now out of print. If you cannot locate it in your library, send me a PM nad I'll see what i can do. Jethro's star pupil, Don Sternberg has made some wonderful CDs.
You should also seek out a CD by Johhny Staats and Robert Shafter called "Pickin' Up Steam".
If you have to work solo, you need Jethro Burns Book ( Mel Bay) and get a hold of his classic CD "Tea For One". Look up Mandolin Cafe for further material by the likes of Dix Bruce.
