At Arcade Fire’s concert in Mountain View, California Wednesday night, as the band finished playing “Neighborhood #1,″ a man proposed to his girlfriend in the front row. When Win Butler saw what was going on, he handed the man his microphone and began to sing to the couple.

Proposals at concerts have been popular lately, happening at a Paul McCartney show and Bonnaroo as of recently.
