T&S "I know, I know, I know" adoreable little girl in audience sings along

[@rendiculousness]

I love it. So many performers you see FLIP SHIT when someone tampers with any aspect. Tegan and Sara went along for the ride and enjoyed their young fan. It only makes me love this band more. Very impressive!

[@sabrina27ize]

hahaha at the very first when Sara was singing the backing vocals I thought it was actually the little girl and almost fell off my seat. I was like "HOLY CRAP SHE'S GOOD! SHE SOUNDS LIKE SARA!!" then I realized she actually starts singing at around 0:15 LOL
