Hmmmm, well, it depends on what you mean by "sword fighting"
If you mean fencing, well generally that is non-contact, and would be a pest I think, even if you were able to put a bleeper or other device on your opponent's phoyle, sinse in fensing with a rapier, as you always attack with the point, you very rarely touch your opponent's blade for a long time, and as the phoyle's are very fast and thin, they move very quickly.
fencing with a sabre or broard sword might be more manageable, sinse the weapon moves more slowly, and your more often in contact with your opponent's blade, but if you know people have done it, ------ why not ask them? or was it just a one time only publicity or awareness thing.
About the closest I've come is dancing with a cutlass, and a small amount of on stage fighting, but sinse that was all pretty much set, there wasn't too much difficulty other than remembering all the appropriate moves.
With our dreaming and singing, Ceaseless and sorrowless we! The glory about us clinging Of the glorious futures we see,
Our souls with high music ringing; O men! It must ever be
That we dwell in our dreaming and singing, A little apart from ye. (Arthur O'Shaughnessy 1873.)
