Dang, i've never thought of that question.. I was always thinking weather zac or josh or jeremy left.. but never hayley. AH, knock on wood. But i would probably still listen to them. But if they do continue as a band if Hayley did leave, they really need someone GOOD to replace her. Even though it really wouldn't be the same.. AHH. I HOPE SHE DOESN'T LEAVE! I'd probably cry for months.
