Major star power tonight both off the stage and on it, as U2 played its third of eight shows at Madison Square Garden in New York City. The audience was filled with celebrities and politicians, as you'd expect, but the real story was the stars that joined U2 on stage: Jimmy Fallon and his Tonight Show band, The Roots. We won't get into too many details in case some of you are still avoiding spoilers, but it looked and sounded like one of the most fun moments of the entire tour.

If you do want the details, well, check out the setlist on @U2 Tours. If you were at the show, look for the "Post Review / Photos" link to share your thoughts and pics with us.

Next up? New York #4 on Thursday night!

UPDATE: Here's a great video of that special performance mentioned above!
