Does anyone recongnize this song?

4 (or more) african americans with green suits and the stage is filled with green hearts all the women admire them.The music video starts with an announcer saying the band's name and everybody cheers and then it turns to color.The chourus is it think "Shaaaaaaaalaaaaaaaa,oh oh,shaalaaaa!" and there is also a part where someone says "shake it shake it.Can you tell me the name of the song"
