Of Montreal played “An Eluardian Instance” on Letterman last night. I think “Id Engager” might have been a better choice, but this one made great use of Dave’s horn section. Also I do have to say that Dave, against his better nature, did make a funny. After the performance — which includes lots of stage antics behind the band — was over he went up to Kevin and said “Boy, you should have seen what was going on back there!”
