A photo has surfaced that appears to show Mike Gordon, John Mayer and Bob Weir rehearsing together. We’re not entirely sure what the trio are working on, but Mayer and Weir recently performed together when Mayer was the interim host of The Late, Late Show.

It’s also been rumored that additional reunions with the surviving members of the Grateful Dead would not include Phil Lesh, thus creating a potential role for Gordon to perform. However, the rumored dates in June conflict with the recently-announced solo tour from Mike Gordon.

Incidentally, the photo is also very reminiscent of the recent photo shared by Grateful Dead drummer Mickey Hart, showing Weir and Steve Kimock working on a collaborative project.
