A young man in a white T-shirt dances to the sounds of 4 men playing brass instruments on a stage.
The man is a groupie of the band.
Just because this young man is dancing to the sounds of 4 men playing instruments on stage does not mean he is the band's groupie. He may  just be a drunk young man enjoying the music.
