I noticed in the musical OLIVER! that people in the background of the pub were singing a song that sounded very similar to "Sweet Betsy from Pike." I soon discovered that "Sweet Betsy from Pike" had its English roots as "Villikins and his Dinah." That is most likely what the people in the background were saying. If any of you have a copy of OLIVER!, go to the scene where Fagin goes over to the pub and asks Bet about Bill Sykes. Listen carefully to the music in the background and you will hear it.
