This is the version we sang in the playground in the fifties-

Sambo had an auntie and auntie very poor
One day she said to Sambo get down and scrub the floor
Sambo feeling tired went upstairs to bed
Tried to climb the banister and fell down on his head
Crash bang

Chorus
More work for the undertaker
Another little job for the tombstone maker
Down in the local cemetery
On his tombstone you will see
Sambo the brave and free

Sambo had an uncle and uncle very rich
One day he said to Sambo I'll give you 2 and 6.   (two shillings and six pence)
Sambo feeling thirsty went into a shop
Five lemonades and six ginger beers
And his belly went off pop
Crash bang

Chorus
More work for the undertaker etc.

Sambo joined the railway he'd a blue and purple coat
Tried to polish the railway line with a piece of mouldy soap
Saw the engine coming stood right in his tracks
Rolled up his sleeves and slapped his knees and pushed the engine back.
Crash bang

Chorus
More work for the undertaker etc.
