I'm thinking of "Come and I will Sing You," which is a Christmas Carol, a cumulative song, and also a counting song. Its final verse (in one version) ends:

Twelve, twelve Apostles,
Eleven is the eleven that went straight to heaven,
Ten the Ten Commandments,
Nine the bright eyed shiners,
Eight Gabriel angels,
Seven, seven stars under the sky,
Six, the six pallbearers,
Five ferrymen under the bush,
Four Gospel preachers,
Three of them were drivers,
Two of them were lily white babes, clothed all in green-o,
One the one that's all alone and ever more shall be so!

Also, Eliza Carthy's Acres of Ground from the Imagined Village CD has something in common with the above. Does this meet your needs, or does it really have to be almost all numbers? Let us know, as there are lots of songs like the above that Mudcat members will know.
