My son also pulled it up during a PPO reservation at BOG last week . It was a great surprise, as both my boys have tried dozens of times before to no avail!! Big brother was very jealous ;-)
The show was just a quick little (10 minutes many) thing with a man and woman.
They are the Royal Majesty Makers.
I'm not sure how often their sets include the Sword show.
Here is their schedule.
