T Henson Co has 1 On the Bus concert.

In 1964 Ken Kesey had a problem. Every time the bus would stop for gas or something, some of the Pranksters would wander off and whenever it was time to leave, at least one Prankster could not be found. Hence the metaphor, "You're either on the bus or off the bus." Of course, no outsider had any idea what Kesey was talking about when he said that, because you had to have been on the bus that summer to get it. During this time a few friends of Kesey were putting together a little rock band in the bay area.
