On Taylor Swift’s current neverending RED arena tour, she regularly brings out artists who she’s a fan of, so she can dork out in front of the hordes of teenagers who are dorking out in front of her; it’s, to my mind, a deeply endearing tendency. That ever-expanding list of artists is a wide and kinda-weird one: Carly Simon, T.I., Jimmy Eat World frontman Jim Adkins. And last night at L.A.’s Staples Center, she introduced Tegan And Sara, who sang “Closer” with Taylor. The wave of kid-screams when Taylor yells their name is the sort of thing that might make you feel good about the future of the world. Two things to pay attention to: Taylor’s dancing, which is absurd, and the fact that Taylor is about a foot and a half taller than either Tegan or Sara, which is visually interesting. Watch the fan-made video below.

If we all visualize a universe in which Taylor brings Kathleen Hanna out onstage, maybe we can make it happen.
