Army of The Nile
This march is frequently played at a significantly slower tempo than straight 112 per minute (which is, I believe, the standard Brit "quick march" tempo). I believe the Brits have a term for it, but I've long since forgotten it.
At any rate, I've played this march so often it's STILL a head chart!
