The devolution of Tegan and Sara from cool indie lesbians to Liz
Phair-esque pop stars officially occurred Tuesday night in Los
Angeles, when Taylor Swift had the duo perform their single
"Closer" during one of her shows.  "If you've ever had your
heart broken, you need to have their album," said Taylor in her
one-line back cover review of their music. Tegan and Sara sound
great and if you enjoy watching Taylor Swift dance in hot pants,
you'll like this performance.
