The Uneven Bars Developments (50s-2010s) - YouTube
I had never seen bar routines from the 50's - I burst out laughing! I thnk my favorite era is teh late 70's thru the 80's when the bars were still fairly close together and they could catch the lower bar with their hips and do back cirlce cathces. It made for an elegant transition from high to low and back again. Todays version is much closer to the mens high bar.
