WATCH: Indie Royalty Tegan & Sara Sing Backup For Macklemore’s “Same Love”

Montreal’s Osheaga Music and Arts Festival drew record crowds to the city’s Parc Jean-Drapeau last weekend. Despite last-minute cancellations from R&B stars Frank Ocean and Miguel, the three-day festival managed to attract over 135,000 people to headlining sets by The Cure, Beck, and Mumford & Sons.

But the weekend’s most viral moment comes courtesy of Macklemore—obviously—who invited the legendary indie lesbian duo Tegan & Sara (you know them, don’t embarrass yourself) on stage to sing the chorus of his marriage equality anthem, “Same Love”.

Asking T&S to sing the lyrics of your groundbreaking single about gay love is like asking Cher to officiate your gay wedding. It really doesn’t get any better (or gayer) than this, folks.
