Toronto indie-pop act Alvvays have had a breakout year, and here’s the latest evidence: Saturday night, during a benefit show for Seattle area arts nonprofit Power2Give/Puget Sound, Ben Gibbard sat at a piano and covered Alvvays’ signature song “Archie, Marry Me.” Instagram user Dusty Henry captured a few seconds of the performance, which make me want to hear the whole thing. Watch below.

UPDATE: Henry has uploaded a longer clip to YouTube:

Alvvays’ self-titled debut is out now on Polyvinyl. Gibbard has a new Death Cab For Cutie album coming next year on Atlantic (read our recent interview with the band) and a Postal Service concert film out on DVD 11/24 via Sub Pop.
