Please help me find this song!

Can't find a song, please help me! Woman singer, video starts from old man sleeping on a metal bed in the middle of the white room. group of young women (cheerleader style) and young people with music instruments appear from behind the white curtain and stand in circle around him. Music starts, old man is confused throughout the video. Woman also stands there and sings. If I remember it right, colours are mostly white + bright colours. I heard it at least 4 years ago.
