To the OP:
They are looking at changing the "characters" in the Legends Show.
They have to wait until the contracts expire for the rights to use these character's likeness and music.
Plus, the expense of the costumes themselves ... since they have costumes to fit ANY size for 10 singers.
Plus we do get paid.... a free DVD of the show and a free group picture.....plus the fun which is priceless.....LOL
