Collaborated and traveled with
Bob Dylan in the 60s, including the
chaotic tours documented in the movies 'Don't Look Back' and 'Eat the
Document'. He also filmed the Monterey Pop Festival, went to Woodstock
and traveled to Nashville with a then-struggling songwriter named Kris
Kristofferson. He later co-wrote the song "Mercedes Benz" with
Janis Joplin.
