Further to John Routledge's posting of July 18th 01 (!) I have just been involved in shooting a short film at the Journal Tyne Theatre in Newcastle and their historical display says that the song The Lampton Worm was written by C.M.Leumane for their first panto, titled The Lampton Worm, in 1867 (John's 1857 may have been a typo).
