"Roll me over in the Clover" gee, one of my sisters TAUGHT that to people at Briarwood one summer in the 60's. Being good Episcopal children *WE* learned it from our parents...From talking with others I have since learned it was popular during WWII, (veterans were the ones who told me) and some of THEM are pretty sure they learned it from WWI vets. don't know how far back it goes.

Another variation is "Put your shoulder next to mine and pump away"
