Against the spectacular backdrop of Edinburgh Castle, the nautical-themed 2011 Royal Edinburgh Military Tattoo features a wide range of performers from four continents, from the Commonwealth, Europe, the Middle East, South America and, of course, a strong home-based contingent.This action-packed programme of highlights features exciting displays and music from the Massed Bands of Her Majesty's Royal Marines, the Brazilian Marine Corps Band, the German Mountain Army Band, the Dutch Mounted Bicycle Band and Fanfare Band and the Tattoo Highland Dancers from Scotland and Northern Ireland.Being the principal service at this year's Tattoo, the Royal Navy presents its famous field gun display on the Castle Esplanade - a time-honoured test of physical fitness and team spirit.A particular highlight and favourite is the stirring music of the world-famous Massed Pipes and Drums and the contrast of the Lone Piper performing from high on the Castle ramparts.The programme is narrated by Bill Paterson.
