Can you guys recommend some more advanced level song books? I just started ukulele, but having played guitar and mandolin for 20 years I'm past the level that most of the songbooks are written in. Not for playing chords obviously (which is great fun on the uke), but the tablature and/or standard notation is melody only if it is included at all. Ideally something that includes bands like The Beatles, Bob Dylan, etc. Country and bluegrass would be good also. Just looking for something more advanced than the many beginner level books that seem to be out there.
