The waitstaff at Black Barts also provides the entertainment, singing a variety of show tunes and other popular songs. Usually only one singer/waiter at a time was on stage, but for one song almost all were on stage.
I requested the Major General song from The Pirates of Penzance, but was told that the person who performs it was not working that night.
However, the highlight for me was the menu, which was limited but which used my font Salloon.
Here is another page with more examples.
I have no connection with any of the other fonts used on the menu.
