Two comedians stand on a set. One is blacked up and speaks with an affected African American accent. They make a couple of jokes and then play a tune on trumpet and trombone. The white comic sings a song called possibly "It's a million to one, you're far from home." He plays a trumpet solo as if he is crying, his made up colleague starts to cry in a comic manner too. They pick up the tune in a jolly manner once more.
N.B. This may be the comic duo - Jackson and Blake.
