Sorry we don't know, but I am pretty sure they take the same name regardless of who is in the band. They might even have the same name on all of the Carnival ships (i don't know, but I wouldn't be surprised).
I am just saying it is hard to track the speicifc musicians down - if that is your goal. I am guessing you liked the band and want to look them up?
I am the editor, but I also speculate, ask questions and play devil's advocate. I reserve the right to change my mind.
