From Rocket Man to Kingsman: Elton John has joined the cast of Kingsman: The Golden Circle, the sequel to the 2015 spy flick about a street tough turned secret agent.

The English musician confirmed recent reports with an Instagram post declaring that “Wednesday night’s alright for fighting” — no doubt a nod to his 1973 song “Saturday Night’s Alright for Fighting.”

John boards a cast that includes returning stars Taron Egerton and Mark Strong and newcomers Julianne Moore, Channing Tatum, and Halle Berry. The Fox production has also strongly hinted that Colin Firth will be back as well, despite the fact that — spoiler alert — his character appeared to meet a grisly fate in the first film.

The sequel will continue the adventures of Gary “Eggsy” Unwin (Egerton), a former London delinquent who has been trained to save the day by a secret spy organization.

Returning director Matthew Vaughn has had his eye on John for a while: He told ABC News Radio last year that he wanted the Grammy winner to appear in the the first Kingsman movie, for “a whole fun subplot about celebrities being kidnapped.”

Vaughn continued, “I had an idea of, ‘Who’s the worst celebrity you’d want to have locked in a cell?’ And I came up with Elton John, and having Elton John throwing these huge tantrums. And then I wanted to do an action scene of Elton John kicking the living daylights out of people.”

He may yet get his chance. Kingsman: The Golden Circle is scheduled to hit theaters June 16, 2017.
