More problem finding band names that haven't been taken before, than personal nommes d'etage. My friend and I have appeared as the Crazy Cousins (with a nod to the Silly Sisters). I drew the line at being Krazy Kousins - too much like a Krispy Kreme doughnut!
Then at Girvan Trad Music Festival each year they have a very unserious Folk Band competition: we entered as "Loosely Connected": next year, with slight change of line-up we were "Even more Loosely Connected" and by 3rd year "Just Falling Apart".
