When you grow up what will you be There's so many jobs just look and see Maybe we'll be train engineers when we grow up An engineer drives a train Through the wind and snow and rain Let's all drive the train Blow the whistle and say 'choo choo choo choo' Maybe we'll be clowns when we grow up A clown can dance and wiggle Make you laugh and smile and giggle Let's all do a silly dance Do a silly dance and wiggle wiggle wiggle Maybe we'll be musicians when we grow up A musician plays in a band Spreading music all across the land Let's all play in a band Banging drums and say 'poo poo poo poo' When you grow up what will you be There's so many jobs just look and see
