Mitch asked here; awryone says no.
(ETA: He [and P&S] first played “Sweet Caroline” spontaneously, prompted by audience banter, at the Birchmere, last August — JoCopedia tells the story. He also played it with Supergroup, JoCopedia link. He seems to play it because it gets a good reaction [because it’s known from sports], rather than because he himself likes sports.)
