I'm not even sure the paycheck would be that much more significant. DTP's recent skyrocketing in popularity is a little bit astounding to me (and great for him!). I'm continually surprised at how many younger kids I see who LOVE Devin Ziltoid-present (and who are only vaguely aware of his work prior to Ziltoid).
I saw SYL in '06 on their farewell tour, and they played a pretty small place and it wasn't a full crowd even with that show being combined with another intersecting tour (i.e. two crowds at one show), and with it having been already announced as the last SYL outing.
