This is a musical number from the second act of Monty Python's "The Meaning of Life". Please keep in mind the Catholic who is singing the lead does not believe in contraception... and neither do his many, many children, who are singing the backup. And yes, that IS a Chinese dragon in the background of the finale. How it got there... don't ask, don't tell.
Set during the War for Ireland's independence, this 10 minute anime short tells the dark folktale of a 5 year old girl who, as the English army draws near her village, seeks salvation only the Legendary Black Swordsman can provide. Rich in symbolism, this gothic fairytale is a real gemstone in both character design and animation... and it must be seen to be believed.
