Jackass stuntman Chris Pontius and Jackson Browne have been added to the Flaming Lips' record-breaking tour attempt.
The group plans to perform eight shows in 24 hours in a bid to break Jay Z's record of day-long gigs - and their guest list is beginning to look more than a little impressive.
At each of the group's stops, celebrity pals will be joining the Lips onstage.
Already announced acts hitting the road with the band for the 27 June and 28 June (12) shows in Mississippi and Louisiana include Gary Clark, Jr., Grace Potter & The Nocturnals, Givers, Neon Trees and Karmin.
