Update 11:58 PM ET: Phish just welcomed Bob Weir out for six full songs in Nashville. Full details and Periscope video here.

It’s been 16 years since Bob Weir and Phish played together, but it seems that is changing tonight!

Weir has been on his “Campfire Tour,” and is scheduled to perform at the Ryman Auditorium in Nashville, TN tomorrow night. Meanwhile, Phish is kicking off a two-night run at the Ascend Amphitheatre in Nashville, TN tonight. With both artists in town tonight, fans have been hoping for some sort of collaboration tonight during Weir’s off night. It seems that’s in the cards.

According to many reports, Bob Weir was playing with Phish during their soundcheck. Check out this video, which clearly features audio of Phish with Weir accompanying in vocals. The video features a extended jam rendition of “Walkin’ Blues,” a blues standard that Weir has been singing for years.

Here’s another shorter version, just in case the FB video gets taken down.

Fans who are in the Nashville area have also been confirming the news with reports of the soundcheck.
