I believe this video is from a (1959) film based on the career of Red Nichols & the Five Penny's featuring Louie (Satcchmo) Armstrong and portraying Danny Kaye as Red Nichols.

If you haven't heard of Danny Kaye then you must be very, very young and apparently missed a unique individual. Kaye died in 1987 at about 74 years of age. If you care to research a 1955 film called "The Court Jester" and then try and find his famous "pellet with the poison" speech, it's a hoot.
