I must mention Piper Bill Millen under Lord Lovat and his Lovat Scouts landing on Normandy with Piper Millen playing his pipes to motivate the troops. According to an interview, he was the first man to disembark the landing craft and strike in his pipes and he did wear a kilt, although, in the movie, "The Longest Day", he did not. He played as himself in the movie. That would be D-Day, June 6th, 1944.
