Last month it was rumored that Elton John just might have a role in Kingsman: The Golden Circle, which already features a pretty killer lineup of talent, including Julianne Moore and Channing Tatum. It’s been a bit quiet on the Kingsman front since Tatum’s casting, but Elton John has officially confirmed his involvement with the sequel via a delightful new teaser poster.

Elton John made his casting official with this Instagram post, featuring a poster similar to the ones teasing Tatum’s role and Colin Firth’s return:

That caption refers to John’s role in The Who’s 1975 musical film Tommy, in which he played the Pinball Wizard. And the text on the poster is, of course, referring to John’s classic song “Saturday Night’s Alright for Fighting.”

The iconic pop star hasn’t appeared in a live-action film since his cameo in 1997’s Spice World, making his involvement with the Kingsman sequel kind of a big deal. It’s unclear if his role is that of a protagonist or a villain, however.

Matthew Vaughn is returning to direct the sequel, which follows Taron Egerton’s Eggsy and Mark Strong’s Merlin as they flee to America following an attack on Kingsman HQ in London. Halle Berry will play the head of the CIA, with Narcos star Pedro Pascal as a new protagonist named Jack Daniels, and Channing Tatum in an unspecified role. Julianne Moore plays Poppy, the film’s new villain.

Kingsman: The Golden Circle hits theaters on June 16, 2017.
