Hob Y Derri Dando (And thanks for the Welsh version, Gareth!)

The Baggies, however use the words from another capstan shanty "Mochyn Du" (Black Pig) to the tune of Hob Y Derri Dando. The Mochyn Du version has the chorus:- "Wuz you ever saw?" Or "Did you ever see, Did you ever see, did you ever see, such a funny thing before?"

You can find a couple of versions of Hob Y Derri Dando in Stan Hugill's book, "Shanties From The Seven Seas."
