Hi!  I've noticed that there are very few music books listed.  I'm trying desparetly to find a Mandolin Tab book that has the song "So Happy Together" as a nostalgia 
type gift for my son.  He played mandolin when he was young, and sold it when he got married.  We're getting him a mandolin for his birthday, and that was his 
favorite song!  I've searched the net all over and hoped I might find something here.  If so, please send me a pm.  Its a guarenteed credit! :)
