On our way to the National Archives Gift Shop, we came upon a Royal Marines Band performing at the United States Navy Memorial. For those that have access, I have posted a couple of videos on my Facebook page.
From Wikipedia, "Today all Royal Marines Bands are required to provide every imaginable musical ensemble including orchestras, quartets and dance bands, as well as traditional Military (marching) Bands. To achieve this, all RM musicians, except solo specialists, are required to attain an above-average standard on both a string and a wind instrument. As a result of this special versatility, Royal Marines musicians are recognised around the world as being both thoroughly professional and highly-talented within the military musical world. The Corps of Drums receive an equally thorough training and pride themselves on maintaining the highest standards of drill, bugling and drumming. Their glittering presence at the front of all Royal Marines Bands on the march gives the bands a visual impact that is second to none."
