It's been going since 1815, and Langholm Town Band is celebrating its 200th anniversary in style, by performing in Edinburgh tonight.
The band's been invited by the Royal Edinburgh Military Tattoo to Usher Hall, where they will bring the Battle's decisive moments to life through a dramatic musical and theatrical performance.
They will perform on their own, and with a 300-strong massed band:
This is a performance with personal significance for the band - their first significant appearance was for the return of the Scots Greys, from the battle.
The officer commanding the Royal Scots Greys was so impressed, he presented the band with part of the brass from his horse's harness, which is now known as the Band Buckle.
