We already told you about John Mayer’s good time at Phish last night, but it appears as if there was another famous musician in the house to check out Phish’s Las Vegas spectacle. Mike Gordon posted a couple of photos of himself with Mayer backstage as well as Radiohead guitarist Ed O’Brien, who dropped in to chat with Mike and Trey Anastasio.

Even more impressive, it seems as if O’Brien picked himself up a poster on the way in (or out) of the MGM Grand Garden Arena. The connection between Radiohead and Phish almost met directly on Halloween in 2009, when Phish listed numerous albums on their website as candidates for their Festival 8 set, Radiohead’s masterpiece Kid A being among those choices. The honor would later go to another British group, The Rolling Stones’ Exile on Main Street. 

And of course here is Mayer in full costume with Gordon.
