Ten green bottles sitting on a wall revisited.

Ten craws sitting on the Mausoleum

Ten craws sitting on the Mausoleum

And if one craw should accidentally fall,

There'll be nine craws sitting on the Mausoleum.

Nine craws sitting on the Mausoleum

"Ten Green Bottles" is a popular children's repetitive song that consists of a single verse of music that is repeated, with each verse decrementing by one the number of bottles on the wall.
