Well, I have heard that about pipers...

When they came to the crossing which later became known as Pegasus Bridge, troops on the other side signalled frantically that it was under sniper fire. Lovat ordered Millin to shoulder his bagpipes and play the commandos over. “It seemed like a very long bridge,” Millin said afterwards.

The pipes were damaged by shrapnel later that day, but remained playable. Millin was surprised not to have been shot, and he mentioned this to some Germans who had been taken prisoner.

They said that they had not shot at him because they thought he had gone off his head.
Hehehehehe.....
He met Lord Lovat while he doing his commando training at Achnacarry, north of Fort William. Lovat, the hereditary chief of the Clan Fraser, offered him a job as his batman, but Millin turned this down and Lovat agreed instead to take him on as his personal piper.

The War Office had banned pipers from leading soldiers into battle after losses in the Great War had proved too great. “Ah, but that’s the English War Office,” Lovat told Millin. “You and I are both Scottish and that doesn’t apply.” On D-Day, Millin was the only piper.
