Smith officially left the band last year, with an open letter to fans detailing a battle with addition.

That wasn’t the only special guest who appeared during the show. Fall Out Boy’s Pete Wentz also made a showing, to wave a flag around through ‘Victorious’. Got to find something to do with your evenings, right Pete?

Also @petewentz came out and waved our victory flag for #Victorious #thankspete pic.twitter.com/gXR3IQ0sPk
