She may have felt sorry she had to postpone but she wasn't sorry that she slayed in the rain for 55,000 people. If you think Taylor is good normally, there's something about rain that makes her step up her game...it was insane. That must be why she's always writing about it so much.
The best part of the whole rain thing was that it started when she was singing about rain during Fearless and then carried over into YBWM, Dear John, Enchanted, Haunted, Long Live...which is arguably the best part of the concert. Iconic night forever.
I was there the next night too and she still slayed hard but it simply couldn't live up to the night before.
(And I'm afraid nothing will live up to that night.
