Duff McKagan may have had the best seat in the house during Faith No More's April 23 performance.

As you can see in the fan-shot footage above, Faith No More singer Mike Patton told the audience that McKagan had joined the band for the evening — albeit masked in the distinctive leather garb worn by the silent gimp who's been a constant presence in their recent shows and promotional shots.

There's obviously no way of knowing whether Patton was really serious, but if McKagan wasn't actually in the suit, he's doing a pretty good job of playing along on social media — the day after the show, he tweeted out a photo of himself dressed for gimp duty:

Faith No More are currently on the road warming up fans for the May 19 release of Sol Invictus, their first album of new material since 1997's Album of the Year. The band released the first single from the album last fall, which you can sample here.

McKagan, meanwhile, has been plenty busy on his own: His band Loaded ended a two-year stage hiatus with a benefit gig in early March, and he recently recorded a new song with his former Guns N' Roses bandmate Izzy Stradlin. Plans for the song seem fairly vague, but McKagan hinted at the possibility that it could lead to more collaborations between the two, saying, "We’ll probably do it some more. We’re gonna maybe record some more. But we just enjoy making music together and enjoy each other’s company. We’re allowed to do that."
