P.S. I love how we are all weighing in on this with one opinion or anther. I haven't seen people this divided (and devoted) since Mwoo.
Bwahahaha, and I remember how chaotic that was!
I'm going to focus on the positive for a minute and say that Piggy looked and sounded fabulous, and I thought it was nice to hear them singing "Don't go breaking my heart", since we all know it was done on the muppet show; I think it's great to have a throwback like that, and also a good idea to perform something tried-and-tested successful on such a big stage.
But, I am in the boat of "Where was Steve?" I don't mean it in a mean way, like "it's stupid that he was gone!1111!1", which a few very passionate people have expressed here already (and good on you! Keep that fire a-burnin, it's nice to see). But I personally was thinking more along the lines of "What reason would keep Steve away from such a (relatively, compared to other recent performances) high-profile gig?" I don't think it would have been a deliberate decision to use a stand-in unless he
couldn't be there, since Piggy/Eric Jacobsen was the real deal.
