I screwed up when replying to this a few weeks ago--obviously, the spammers are not the only ones thwarted by the "enter the text above" thing! Oy vey... Must pay attention.
Anyway, we never watch the whole Grammy's because they're nuts and bloated. We always tape them and fast forward to the neat performances (though the mash-up thing is overdone). With that, other than Sly and his bad posture, I enjoyed just the performance of "One" by U2 and Mary J. Blige.
