Watch: John Mayer just mashed together Grateful Dead’s Dark Star with Your Body Is A Wonderland

John Mayer treated fans at a show in Chicago last week (18 October) to a mash-up of Grateful Dead’s Dark Star with his popular track, Your Body Is A Wonderland.

Mayer has toured alongside members of Grateful Dead since 2015 as part of their Dead & Company supergroup consisting of members Bob Weir, Mickey Hart and Bill Kreutzmann, alongside Oteil Burbridge and Jeff Chimenti. He took part in his final tour with the group back in May.

At the show, which took place at the United Center, Mayer introduced the mash-up and shared his pride in doing so: “I’m not going to set it up, this is going to be the weirdest thing you ever saw in your life and I’m proud to do it,” he says in the footage shared online by fans.

“I want you to mark it on the setlist that this is technically Dark Star. And I’m going from Dark Star into this next song. It’s a transition. I want you to mark the transition.”

After the performance, he adds, “You know what that just was? And I do this with extreme love for my brothers in company. With all love and reverence, that was Dark Star/Your Body Is A Wonderland/Dark Star.”

At the same show, he also performed Grateful Dead’s Bertha for the first time solo, and combined it with his track The Age Of Worry, according to NME.

In other Mayer news, the sob-rocker was recently gifted a guitar built from wood taken from the floor of Madison Square Garden. The unique axe was made to celebrate his two-night stint at the iconic venue, and was commissioned by The Garden and made by Charvel Custom Shop Master Builder, Joe Williams.

The recently-removed New York Knicks basketball court was used to make the guitar, so there’s a sticker displaying the Knicks’ logo on there too.
