Thank the fictional band gods … because Jesse and the Rippers are getting back together. Have mercy!

For those of you who grew up watching “Full House,” you’ll remember that heartthrob Uncle Jesse (John Stamos) was in a rad band called Jesse and the Rippers that practiced in Danny Tanner’s basement. Jesse Katsopolis was the guitarist and lead vocalist, who also owned a club called the Smash Club. The club was successful and the band ended up kicking him out when he got to wrapped up in it, leading him to form a second band – Hot Daddy and the Monkey Puppets.

Well, it appears that Jesse is back on good terms with the Rippers, and the group will be reuniting for a special gig on “Late Night with Jimmy Fallon.”

Stamos, who played Uncle Jesse for eight seasons, teased fans with an Instagram video, posting: “Never thought I’d be singing THIS song.”

The song in question is the “Full House” theme song, which was originally performed by Jesse Frederick, who also helped compose theme music for other '90s sitcoms, “Family Matters” and “Step By Step.”

Besides the performance on “Fallon” being confirmed by People, the fictional “Jesse Katsopolis” (@jesseandtheripp) has also been hinting that something is in the works. “Less Than a week --- RIPPERS STORM NYC !!!” he tweeted on July 13. On July 15, Katsopolis tweeted an old photo of him wearing a leather vest, writing, “have to dig this vest out of storage – may need soon.”
