I seem to recall that "The World Turned Upside Down" was played at Yorktown When Cornwallis surrendered. However we're getting into areas where legend and history tend to merge. Indeed it was a marching song and I took that someone played it but I was never clear as to whom. I assumed the British but it may well have been the Americans many of whom fought in the French and Indian war(Seven years war for our European catters). The first cross to rock & Roll or Blues from folk was the old song Stagger Lee in the '50s. My older brother used to play it at his parties. I, being 4 or 5, was supposed to be in bed. The "evils" of rock and roll proved much more entertaining. reguards neil
