This appears to have been the melody of a song. From Colonel St. George Tucker, serving with the Virginia Militia, at Yorktown Virginia, 1781 - "This morning at nine o'clock the articles of capitulation were signed and exchanged. At Retreat beating last night the British played the tune of 'Welcome Brother Debtors' - to their conquerors the tune was by no means disagreeable." Elsewhere, he logged a British bagpipe serenade. Taken from the article: "If ponies rode men and grass ate the cows" Just What Tune was in the Air when The World Turned Upside Down? by Dennis Montgomery - American Revolution.org
