Cover art for Monsoon lyrics by Robbie Williams

Imo he talks about his life after he was famous. He feels he is just having a good time and he wonders how comes he is liked so much. He understands that the fans also are having a good time along with him so he asks them to just have a good time (So put your hands across the water Oh mushroom) and explode (Monsoon Come soon). So put your hands across the water Oh mushroom Monsoon Come soon!
