Okay, well I don't think the song is that old.
And all I can remember of the video, is its on a beach in the sun, with palm trees etc, and there's a big crowd of people.
And either a kid begins the song, or comes in at some point singing it, getting on stage, getting the crowd going to. Im sure he has an accent, Jamaican perhaps. Its quite an upbeat song.
Please help, its annoying me so much. Was on the music channels a lot too I think, because that's were I saw it.
