black eyed peas performed a special live version of “i gotta feeling” for oprah while a flash mob of synchronized dancers groove on michigan avenue in downtown chicago, il usa. the performance was for oprah’s 24th season kickoff party on september 8, 2009. flash mobs are not all that new, but this one caught my eye. at first, i thought the woman in the front row was being paid to “fire start” since others were just standing in boredom.
