Loking for the lyrics (and tune) these are the words I remember

Shu la la ~ Shu la my foot rocks the cradle
Sleep till the morning light creeps o'er the cill
Shu la la ~ Shu la, I work when I'm able
Turning a collar or gathering a frill.

I heard a lady sing it at Towersey, must have been about seven years ago and it's haunted me ever since.
