Thanks for solving! I didn't realize that about the actual band name. Looking back at the clues for 22A and D, I see that they're harder than the rest of the puzzle. Maybe I'll keep 22A as is (I like the crytpic-ish approach to it instead of just cluing it as to and __, or something like that) and make the 22D clue more obvious.
The SEMI-NOLEs (groan)... I'd say including NOLE was worth the pun, but I would've probably filled that corner with crosswordese OLEG over crosswordese NOLA, crossing TELL and EGAD.
