Three Ring Circus Dean & Jerry Sing " Hey Punchinello"

Here is the big musical scene from the movie. I still wonder why they left this movie out of the Martin and Lewis DVD Collection Volumes 1 and 2? Aren't there any copies left to make a DVD of it? I heard that the tension between Dean and Jerry reached a head during the filming of this movie and that Jerry was starting to get interested in directing the films himself. Perhaps this may have had something to do with it if Jerry himself was involved in the selection process.
