I'm trying to locate a song, probably called Please Don't Sell My Baby's Chair. It concerns a woman whose possessions have been siezed by the bailiffs and put up for auction.

With each item that's placed on the block, the woman tells the auctioneer to take it if he must, but she begs and pleads with him to leave her her baby's chair.

Hard hearted auctioneer works his way through the entire list of items, until finally the baby's chair is the only one left. That too goes under the hammer, and the song ends:

"Then up stepped a docker, a Birkenhead docker,
And he knocked down the auctioneer."

Does anybody know it?
