Went to the Black Eyed Peas concert last night with my niece.
It was soooo much fun. At first people were really corny and not standing up, but eventually everyone did. They ended with Let's Get Retarded (Let's Get It Started) and it felt like one big party! [See picture above.]
They are all such great performers. I would definitely watch them again. They know how to please and get the crowd really involved.
