Hoo boy, I don't think so. It might still be in some older libraries, as it was edited by Jane Yolen. The antho was called Werewolves, the story "Monster Mash." I did another girl/werewolf story, with vampires, in Bruce Coville's Bruce Coville's Book of Spine Tinglers called "What's a Little Fur Among Friends" but that one doesn't have a band. The Monster Mash one was my first published story. I'm afraid to read it now!
