The crowd at the Oprah taping in Chicago did a special flash mob dance to the Black Eyed Peas live performance of the song, "I Gotta Feeling." The group dance on the Michigan Avenue in downtown Chicago was really cool to see from the Tribune Tower's 14th floor. This is for Oprah's 24th Season Kickoff Party.

I gotta feeling that tonights gonna be a good night,
That tonights gonna be a good night.
Lets live it up.
I got my money,
Lets spend it up.
Go out and smash it.
Like Oh My God,
Jump off that sofa.
Lets get get OFF,
I know that well have a ball,
If we get down,
And go out,
And just loose it all.
I feel stressed out,
I wanna let it go,
Lets go way out spaced out,
And loosing all control.
Fill up my cup,
Mozoltov,
Look at her dancing,
Just take it off.
Lets paint the town,
Well shut it down.
Lets burn the roof,
And then well do it again. (less info)
