• If "Oh! Mr Porter" is Marie Lloyd's best known song on a train theme, "What Did She Know About Railways?" is the most daring. A young girl from the provinces - a farmer's daughter - arrives at London's Euston Station on the midnight train, and she tells the guards and porters she's never had her ticket punched before.
  
  The innuendo here is obvious, and it was songs like this that led to her appearing before the Vigilance Committee. The sheet music does not appear to have been published during her lifetime, but it was included in the Marie Lloyd Song Album which was published c1954 by B. Feldman of London and by J. Albert of Sydney, Australia. The National Library of Australia credits the words to C.G. Coates, music by Bennet Scott and rev (presumably revised) by Dudley E. Bayford.
• Somewhat surprisingly this song was recorded by Dusty Springfield half a century and more after Marie's death. >>
