The theme is rock and roll so, as you can imagine, the songs are all quite a bit alike. But they will stir up memories in the parents and grandparents in the audience and the kids have had a blast learning them. It should be fun. The hardest thing we have to do, musically, is not play so loud we drown the kids out. Other than that it is pretty much I, IV, V, I chords with a few key changes.
