Listen to Arcade Fire on iHeartRadio | Listen to Rolling Stones on iHeartRadio

It turns out the last time Arcade Fire's Win Butler sang "The Last Time" with Mick Jagger wasn't actually the last time.  Butler took the stage Sunday to play the early Rolling Stones classic with Mick and the boys during their concert in Montreal. 

The two rockers previously performed the tune together during Jagger's appearance on "Saturday Night Live" last year when Butler and his Arcade Fire bandmates served as the iconic frontman's backing band. 

For the latest gig, Butler appeared to make himself at home on stage.  He strutted out with his guitar, only to set it down after a few licks to grab the mic and partake in a face-to-face duet with Jagger. 

Meanwhile, Arcade Fire has been busy prepping their follow-up to 2010's The Suburbs.  The new album is expected out sometime this year.
