Forty-seven years after the Knights of the Round Table revealed a diet consisting mostly of ham and jam and spam (a lot), Monty Python’s famed part-singing, part-dancing, all-silly take on the Arthurian legend returns to the big screen.

Monty Python and the Holy Grail, which was the highest-grossing British film in U.S. cinemas in 1975 and has gone on to rank at the top end of numerous lists of the best comedies, is back in theaters.

Remaining Monty Python members Michael Palin, John Cleese, Eric Idle, Terry Gilliam and Terry Jones recently completed a series of sell-out stage shows in London, said to be their final performances together. Spamalot, Idle's Tony-winning musical adaptation of Monty Python and the Holy Grail, received 14 Tony Award nominations winning three including best musical.

There'll be a fair number of people who already know the lyrics. All together now:

"We're knights of the round table
We dance whenever we're able
We do routines and chorus scenes
With footwork impeccable.
We dine well here in Camelot
We eat ham and jam and spam a lot."
