Turbine's taken a look at another resident of Middle-earth, one who has some specialised knowledge:

Many festivals come to the Bree Festival-grounds throughout the year, replete with food, drink, and merry-making of all sorts. No festival is complete without dancing, however, and that is where Dance Leader Ada Musgrove comes in. No one in all of Bree knows the dances of the Bree-folk as well as Ada, and she happily imparts her knowledge to any players who can keep in step.

Ada Musgrove was originally created by the designers of The Lord of the Rings Online™: Shadows of Angmar for the inaugural Summer Festival. As new festivals arrive at the Bree Festival-grounds, players should always watch for Ada and the opportunity to learn the dances of the Bree-folk!

Keeping in step isn't easy, either! I've tried!
