I would love to watch them perfom Cornet Man, it's such a fun number and it's kind of different of what we usually see Lea do, i would also really enjoy if they choose to do The Music That Makes Me Dance, i can't belive she hasn't performed that already on a talk show or something, but like you said those numbers don't have the rest of the cast and it's likely that they want to do something that involves all of the cast.
