Bon Jovi's performance of the Grammy-nominated "We Weren't Born to Follow", Grammy winner "Who Says You Can't Go Home" with Jennifer Nettles, and the winning song "Livin' on a Prayer" at the 2010 Grammy awards is already on YouTube.
I'm really undecided about this performance. It wasn't horrendous or anything. I mean, it could have been worse -- but it could have been better too. Jennifer is clearly covering for Jon on the high notes of "Prayer" but that's what basically happens at concerts (with the band and crowd singing for Jon what he hasn't had to since the 80s). If "Always" had won the poll, it would have been more obvious if and where Jon needed "saving".
"Prayer" might have packed more punch with the key change, but I don't know what Jennifer's range is like and this isn't like a Bon Jovi concert with tens of thousands of screaming fans to help out.
Overall, a pretty standard television performance, albeit before a bigger audience.
