MMario, their site does quote the words given by Annegi above and I can get them to fit the reel they give so I don't think that there is a mismatch. Incidentally, I remeber that verse as:

Piggy on the railway picking up sones
Along came an engine and broke Piggy's bones
"Oh" said Piggy, "that's not fair"
"Oh" said the engine driver, "I don't care"
