I originally thought that the opening line referred to a Grateful Dead-esque devotion, in a self-aggrandizing manner, but it's clear from their recent documentary (and the rest of the song, actually) that they're really just riffing on equality. That they're on a stage, but they're just like the people they play for, and that true musicianship and artistic expression includes everyone, and doesn't try to draw a line between performers and audience. They felt lucky to make music, and when you combine that sentiment with the oddball songwriting and delivery of D. Boon, you get magic.
