From the NY Times, regarding the plane flight Dean made last night from Iowa to New Hampshire:

On the flight, Dr. Dean took a brief nap and then had a
long chat with his pollster and his campaign manager,
standing over them in the first-class cabin. Flying with
him was Joan Jett, whose keyboardist handed out free CDs to
the reporters, photographers and lower-level political
aides in coach.

At the rally, vegetable soup and clam chowder was served to
the traveling party, as Ms. Jett followed Dr. Dean to the
stage, and played three songs, including "Crimson and
Clover."
