I was in the Catford Taverners, Brothers Gray, and Four Sqare Circle folk bands and got the Rat Catcher's Daughter from John Foreman when we ran 'Folk Song at the Railway',Railway Tavern, Catford. I know Dave Watts used to sing the song and I have sung it ever since I first learned it, and still do. It always goes down a bomb with every one joining in. I am amazed at how few people know it.
