My favorite version of A Christmas Carol is the 1970 musical called Scrooge, which stars Albert Finney. I don’t know if it’s the BEST version but it’s my favorite.
There are two reasons for this, which are highlighted in the videos below. 1. When Scrooge witnesses his death with the ghost of the future, the townspeople dance on his coffin and sing a song called “Thank You Very Much”. It’s mean and funny all at the same time. 2. At a party the people play a game called The Minister’s Cat. This game makes me laugh – I wish I had that much fun at my parties ;-)
