I figured the Animal drum segment went on as long as it did to usurp the "Just killed a man/pulled my trigger now he's dead" portion of the lyrics.
According to what I read, that was done deliberately to keep the video family- and child- friendly. I have been a big Muppet fan for decades.
PS: it was a sad day for me when Jim Henson died. But apparently, Disney is giving Brian Henson a free hand.
