Music for Harp and Guitar

[GP Grant <s0234576@xxxxxxxxxxxx>]

I'm looking for some impressive numbers to learn/play for guitar and 
harmonica.  I've pretty much exhausted the offerings of Cephas and Wiggins 
(with success) and I am currently looking for new artists/songs to learn.  

I'd like to minimize the number of harp/guitar tunes with a vocal part (because 
neither one of us is much of a singer!) so tunes for just guitar and harmonica 
are preferred.

Any suggestions for tunes to play would be greatly appreciated.  Thanks.

G.
