First of all, thanks for posting the interview.
He's always maintained that he will perform Creed songs on tour. Perhaps my view on this is selfish, but I never saw Creed live so I have no objections to that - I'd love to hear them.
I found it interesting that he made a statement about the break-up. Stapp's always said that the guys announced the split without his consent.
I think Mark and Flip announced it from Mark's home.
Perhaps this is Stapp's way of 'getting one back' at them.
As for the remark about Grohl - tongue-in-cheek.
