Bob Weir
The absolute best moment of this entire film for me was watching Bob Weir of the Grateful Dead go completely ballistic on a girl who was defending protesters who nearly killed a police officer.
People seem to think of the Dead as a very political, hard-drinking, pig-hating band, when in fact, they were somewhat level-headed, buisiness-minded, guys. Granted, they could party, and they did a LOT of drugs, but they were also pretty smart people.
I really enjoyed watching Weir smack down people's preconceptions of what being a "hippie" was all about.
