And here's another clip.
Several light saber duels set to the music of O Fortuna (from Carmine Burana - most people know it from the classic Excalibur or, perhaps these days from Sean Hannity's radio show intro...)
Yoda comes in at the end (it's an eight minute clip) fighting Duku and then the Emporer. Unfortunately I think the action is speeding up so you don't get the full impact of "his" moves.
As a connoisseur of cinematic duels I'd say that some of the scenes hold up and some don't. Obi Wan vs Darth Vader in the original Star Wars is perhaps the poorest - I really, really hate it when they make one opponent perform a spin move - turning his/her back to his opponent - when there is absolutely no reason to do so.
