Music Matchup: Lennon and Maisy Do A Cover Of Robyn's "Call Your Girlfriend"

We first saw this song getting a "remix" on an episode of Saturday Night Live.Then Swedish vocal group Erato did their own version, using tubs of butter to add acoustics to the cover.

After watching YouTube stars (and recently, Nashville regulars) Lennon and Maisy do a super cute birthday greeting for One Direction's Harry Styles (have you seen it???), we chanced upon one of their old videos doing a cover of Erato's version of Robyn's "Call Your Girlfriend."
