The current Arcade Fire tour has been full of musical adventures. The band has been including a wide variety of cover songs at every show, with everyone from Fugazi to Neil Young thrown into the mix. At a recent two-night stop at Chicago's United Center, they paid homage to a whole lotta soul.

The first night of their Chicago stop, the band pulled out a rocking cover of the Bo Diddley classic 'Who Do You Love,' originally recorded in Chicago and released on Checker Records, a subsidiary of the famous Chess label. On night two, they pulled out all the stops by inviting soul and gospel legend Mavis Staples on-stage for what turned out to be an incredible medley of sorts.

As Mavis took the stage, the band accompanied her on a partial run through of  'This May Be The Last Time,' which the Staple Singers recorded in 1955. The gospel standard was, shall we say 'borrowed' in part by Mick Jagger and Keith Richards for the Rolling Stones'  1965 hit 'The Last Time.'

Arcade Fire and Staples seamlessly blended the Staples gospel tune in and out of the Stones classic to create an incredible merger of the two songs. Staples seemed thrilled to be onstage with Arcade Fire, and they certainly seemed equally thrilled to have her there. This was not, however, the first time their paths had crossed. In 2011, Arcade Fire singer Win Butler joined Mavis onstage for a rousing rendition of the Band's classic 'The Weight,' which the Staple Singers had covered in 1968, and has long been a part of her repertoire.
