Will John Mayer be co-hosting the 9pm ET edition of HQ Trivia on Sunday, June 17th? The signs point to yes.

On Wednesday afternoon, the popular quiz show app posted a pair of tweets that seem indicate the Dead & Company guitarist will be joining host—and noted jam band aficionado—Scott Rogowsky on the program. Check them out yourself:

If you didn’t notice, the song playing that second tweet is Mayer’s new single, “New Light”. It’s also worth mentioning that Dead & Company will be playing a pair of shows at New York’s Citi Field on Friday and Saturday, so it’s no stretch to assume Mayer will be sticking around the Big Apple, where HQ Trivia is filmed, on Sunday.

A Mayer sit-in would be a huge coup for Rogowsky, who hasn’t been shy about his jam band fandom during his stint as HQ Trivia’s host. The comedian even dropped by the Governor’s Ball Music Festival earlier this month to bombard crowds of adoring fans with hilarious jam band references that most of them almost certainly did not understand. It’s a tactic Rogowsky also puts to use during his main gig, where he regularly drops Phish references despite being fully aware that they’re going over most HQ Trivia users’ heads.

“Most people don’t even realize what I’m doing—they probably think I’m being fanciful with my word choice when I say, ‘I’m broadcasting live from Gamehendge,'” Rogowsky told Relix back in February. “Sometimes I wonder, ‘Are people Googling that and trying to figure out what Gamehendge is? What is the land of the big baboon? What is he talking about?’ So to me, it’s funny. And I just love that people get a kick out of it.”

Anyway, here’s a hilarious video of Rogowsky doing his thing at Gov Ball:
