By now, most people (or most who'd care, anyway) have heard about the tumble down the stairs Beyonce took at her concert in Orlando on Tuesday. And judging by the number of views on the many videos of the incident -- presumably all posted by the "fans" Beyonce specifically asked not to post the thing -- pretty much everyone who cares has seen it as well.

Seriously. More than a million people have let their fingers do the clicking to watch Beyonce fall down. (I have, too, but that's my job.) If there's one thing that netizens like, it's watching people fall down. That little bit of social observation aside, allow me to say ...

This fall is spectacular.

Beyonce actually manages to fall on her ass, bounce off, and rebound onto her face. Then she gets up and jumps right back into the number. Officially, I'm appalled and concerned, but since her reps have put out the word that she's fine, I can also be impressed as hell. Damn.

It's impossible to tell at this early stage whether Saturday's Live Earth concert mega-event will have the intended effect upon the planet's CO2 emissions. In fact, it seems to have already done substantive harm to the environment. And with 150 artists performing at eleven different venues, there's another kind of pollution generated as well -- the Internet video kind.

Honestly, It's a bit hard to know where to start. But Spinal Tap performed, and then they were interviewed, and that's the greatest thing ever. There's Chris Rock dropping a bad Paris Hilton joke and a F-bomb, to which the BBC reacts by leisurely cutting back to the studio fifteen seconds later. Shakira shook her hips in Germany, and if you've never seen Shakira shake her hips, then you've never seen Shakespeare the way it's meant to be done. And there are very few men in suits who can rock a mike like The Beastie Boys.

But my favorite video definitely has to be Madonna's feisty performance of "La Isla Bonita," as accompanied by two gypsy fiddlers and a pack of rambunctious dancers. Thanks to the blood red lighting scheme, there's a distinctly post-apocalyptic air to Madonna's whole set, but perhaps that's appropriate. Live Earth was a lot of things, but world-saving was not one of them.

Sunday's giant Concert for Diana wasn't so much star-studded as it was star-glutted -- everybody from Duran Duran to Kanye West was there to pay tribute to the late Princess of Wales on what would have been her 46th birthday. But it was Sir Elton John who set the tone. Here, he opens the show, not with his trademark theatrics or the heart-tugging "Candle in the Wind," but with a simple, uplifting performance of "Your Song."

Sir Elton is in fine voice here, but what's even greater is the way he connects with the audience, glancing at crowd and camera as if they are old friends gathered round the piano with him. It's the opposite of mugging -- a peformance that is genuine and personal and absolutely note-perfect for the evening.

That earring, on the other hand, might be a bit much for the occasion. But hey, Elton can pull it off.
