Thanks, John and Alex! Now that I have YouTube figured out, I plan to make some little home videos, as well, and raid the archives for some older performances that were captured on videotape.
I really like the Weeks piece for it's little chromatic arpeggios. None of the turn-of-the-century American mandolinists were really great composers, but some of the pieces are really charming and show off the mandolin well. If you take the best few pieces each by Weeks, Abt, Siegel, et al., then you have a repertoire.
