Ann Wilson is amazing, and most Heart covers of Led Zeppelin songs are pretty great. But as much as I'd love to love their cover of "Stairway to Heaven" from the Kennedy Center Honors broadcast, I can't, because for some reason they chose to cut out a verse or two. I don't remember which or where, because I've never gone back and re-watched it, but I remember clearly singing along with it, and suddenly... WTF? We're not there yet!
I get it, it's a long song. So you cut it from 8 minutes to 7 1/2, which is basically negligible in this context, but destroy the integrity of the song? Sorry, that's just wrong. Excellent performance otherwise, but it's like hearing the edited version of a favorite song on the radio. Someone decided it was okay to just cut this part out. No, it is not okay. If you're going to play the song, you play the song. You don't just play most of it.
Actually, now that I think about it, the Heart version of "The Battle of Evermore" is also pretty unlistenable because they play it so damned slow. Why? It's not a hard song. It doesn't gain any gravitas. It's just too damned slow. Their version of "Rock and Roll" is great, though.
