A musical is being made of Monty Python and the Holy Grail. The movie, a spoof of the legend of King Arthur, did have a few songs — most notably ‘The Camelot Song,’ which contained such famously dubious rhymes as ‘We’re Knights of the Round Table/We Dance Whene’r We’re Able,’ as well as the line that inspired the title of the musical spinoff: ‘We Eat Ham and Jam and Spam a Lot’.”
