Sun Ra and Batman

I just picked up the Sun Ra & the Blue Project album "Batman and Robin." I was in disbelief when I saw it in the record store. Sun Ra doing Batman!? I was all over it. Not as challenging (rewarding?) as other Sun Ra disc, but it's a whole lot of fun. The personal listed doesn't seem to be consistent with what I'm hearing. I heard more horns than just John Gilmore and Marshall Allen; there was a trumpet solo I swear, though no trumpet player is listed. They have two organ and bass players listed, but my ears only hear one each. Does any one have familiarity with this album that could shed some light on it?
