Ha! It was pretty painful for the lonely Broncos fan at the party I went to. (Side note: I wonder why so many Ravens fans flocked to root for the Seahawks -- birds uniting?;-) )
I couldn't hear very well (there were a lot of little kids at the party, who were quite sugared up and boisterous), but from what I could hear and see, Bruno Mars and RHCP did a great job. I was at the Super Bowl last year and thought Beyonce was totally lame. Apologies to any Beyonce fans, but I'm not a big fan of her music, and the performance was a lot of stomping and shaking but not much singing.
Congrats, Seahawks! Nice to pass the championship crown from one port city to another.
