At the start of the 'National Bandstand' dance-off (the "Born to Hand Jive" number), the head of the cowboy decoration in the gym tips forward, spilling wads of paper off the brim of its hat. However, in the establishing shots prior to that there is no paper on the hat brim. In addition, a few seconds later, and as seen in other shots that follow, the head is intact and back in proper position.
