Why would Ralph not play Letterman because of his "Conservitive Christian Beliefs?" Numerous gossple bands play on letterman. Rev. Al Green has appeared twice on Letterman (that I saw). These people have the same beliefs as Ralph, yet don't seem bothered by the appearence. I have the same beliefs and would love a gig on Letterman. I'm looking foward to seeing Ralph play and I'm sure he'll enjoy the gig as much as anybody. His show is one of the best on at any time of day.
