The lyrics, written in dialect, are available from the Traditional Music Library
The Lambton Worm was made famous by the 1867 pantomime song by C.M. Leumane, performed at the Tyne Theatre in Newcastle Upon Tyne.
There is some disagreement locally, whether the worm slept at Penshaw Hill or Worm Hill, however, it is agreed, the worm caused fear and destruction throughout the area during its time.
If you are not a native of North East England you will have to listen carefully to words of the song, to understand the story that unfolds.
