Silent night and twinkle twinkle These were love songs to my simple Little Heart Little Heart Little Heart Little Heart When I grow up I want to be an astronaut I'm gonna grow up And I'm gonna be an astronaut Gonna fly to space Save the human race And do it all with a smile plastered on my face I went marching up a mountain To the stars but then I found this Little heart little heart Little heart little heart When I grow up I want to be astronaut I'm gonna grow up And I'm gonna be an astronaut Gonna fly to space Save the human race And do it all with a smile plastered on my face with this Little heart little heart Little heart little heart Little heart little heart Little heart little heart When I grow up I want to be an astronaut Fly to space Save the whole human race When I grow up I want to be an astronaut I'm gonna grow up and I'm gonne be an astronaut When I grow up I'm gonna be an astronaut Gonna fly to space
