When I was in the Royal Army Service Corps, the regimental march was the tune of an 1850s Southern US parlor/minstrel song "Wait For The Wagon" ~~ it was said to have been a favourite tune of the Boer War General Sir Redvers Buller who originally formed the corps. The Corps no longer exists, having first been renamed the Royal Corps of Transport, and then amalgamated with several other support arms into the Royal Logistics Corps, whose march is called "On Parade".
