No details were given regarding what song Butler would come onstage for, or whether he would just sing, or play guitar as well. Montreal is the hometown for Butler's band.

Popular musical guests from all genres have been a common theme throughout "50 & Counting." Acts have included Taylor Swift ("As Tears Go By"), Katy Perry ("Beast of Burden"), Dave Grohl ("Bitch"), Tom Waits ("Little Red Rooster") and Sheryl Crow ("All Down The Line"). The trend continues from the few shows the Stones played in 2012, which featured guest spots from Eric Clapton, Bruce Springsteen and Lady Gaga.

There is no official schedule of who will join the band where. The last few stars, including Butler and Swift, have been announced a few days prior to the show. Others, like Grohl, have seemingly just shown up.

The Arcade Fire is currently working on its fourth album. Its last effort, "The Suburbs," won the Grammy for Album of The Year.

Butler and his band have previous experience working with Rolling Stones frontman Mick Jagger. Jagger served as host and musical guest for "Saturday Night Live" last May and The Arcade Fire appeared as his backing band. The group played through "The Last Time."

A hint as to what Butler will help play Sunday night?
