Is this all part of the growing up process? First he was a little innocent kid making music decisions based on who he really liked. Then he grew up to be a hipster during the college years. And finally at the end of it all he realized he didn't need others' opinions to validate his own. Just my theory.
i think lady gaga would be a great performance. she's pretty interesting to say the least, and she has a really good voice; it would be a fun show to say the least. i don't think she'll get put on the bill, but if she did, i think people would be generally surprised at her show. before she became the huge pop star she is, she was just a singer/songwriter like all the other females at roo.
