A lot of people were shitting on it because it's Coldplay or because the Beasties stopped playing that song years ago, but I thought it was awesome of them to take a few minutes out of their set to pay tribute. It wasn't a terrible cover either, and nearly made me shed a tear.
I must say, I fucking love his voice, and will miss it dearly if the hormones make it sound silly
EDIT: Ugh. That might have came out wrong. I'm not implying that transgenders have silly voices. I just wonder if he'll keep performing with the band, and if having a new voice will work or not with their music.
