All of the above are definitely on the list. I agree with "Times They are A'Changing" and that will be the song we'll use to kick off the concert. I'm still pulling ideas together and will meet with my friend the banjo player on Saturday. Then I should have something more definite. Even if we do only 2 songs by each of the above -that's already 16 songs and I'll only have time for around 24 - I'm figuring 12 songs maximum per set since there'll be commentary, as well as singing.
