Read the word Wyoming (or may have just even been WY) somewhere yesterday and immediately thought of this gem from Nat King Cole and Stubby Kaye:
Great music to go with a great film and great actors. Lee Marvin as Kid Shelleen (and his brother in a dual role, whom he is hired to shoot) and an absolutely gorgeous Jane Fonda as Cat Ballou. If you've never seen the film, it's well worth watching. But just remember, it's from 1965 so a little outdated compared to today's films, but great fun all the same.
