This clip of Louis Armstrong and Danny Kaye singing "When The Saints Go Marching In" from 1959's Five Pennies is one of my favorite videos to watch; it's a type that turns a poor day into a good one. The enjoyment that the two entertainers have as they sing to each other of the great musical artists is catching. Even more fitting is the very American character of the two men singing, who both came from nothing and despite hardships in their past were able to exhibit such joy and fun and beauty with their music that it helped reveal them as great. Good stuff.
