Well, you guys HAVE to remember, with old rosin the beau's aside, this song IS supposed to be an old standard in the 1350's when The White Company takes place, so it should definately have a medeival sound. Also remember...it was used as a marching song and theme more than a simple tavern songs, so it would probably be more of a bravado, unison type song.

By the Rood, I had forgotten him!
