This popular march was written for the film "The Dam Busters" about the wartime exploits of the R.A.F.'s 617 squadron and their attempts to destroy the dams in Germany's industrial heartland using the "bouncing bomb", a secret weapon invented by Barnes-Wallis. No secret weapons are required to perform this arrangement, just a reasonably able orchestra! Saxophone parts are provided as alternatives (or additions) to the horn parts. The 3rd violin doubles the viola (where necessary at the octave) and either may be omitted.
