Like quite a few people have mentioned, I've not heard of most of these tunes. Red-Haired boy is one I know on whistle, flute, and vocals, but haven't taken the time to learn on guitar.

The one that tends to get attention the most for me is either "Hotel California" (Hell Freezes Over verion, of course), or just fingerpicking the chords to "Suicide is Painless." You'd be amazed at the number of people that just sit there and listen to that song, thinking "Gee, I know what song this is, but I can't identify the melody that goes here."

Then, to really trip people out, I sing it... Hehehe
