Attention, Uncle Jesse fans: Hope you're sitting down.
Jesse Katsopolis – John Stamos's character on Full House – and his band, Jesse and the Rippers, are back ... and they're performing together again Friday, July 19!
The group will appear on Late Night with Jimmy Fallon, PEOPLE confirmed, after Stamos posted a cryptic Instagram video of himself singing the theme song to his beloved 90s sitcom.
"Never thought I'd be singing THIS song," the actor wrote on Monday. And "Jesse Katsopolis" (a.k.a. @jesseandtheripp) has also been Tweeting in anticipation of the TV reunion.
"Have to dig this vest out of storage – may need soon," Katsopolis Tweeted Monday with a vintage photo of himself in a black leather vest, replete with era-appropriate white sneakers. (The Twitter feed also features a trove of photos from the era, including outtakes from the "Forever" video, and hints at another performance as well.)
Stamos, who's currently starring opposite Callie Thorne on USA's Necessary Roughness, has often said he's grateful for the sitcom role that he's still known for today, and clearly he's making good on that assertion.
As to which we must say … have mercy.
