The number one song in the U.K. isn’t Ed Sheeran or Justin Bieber, it’s not even the wildly popular “Old Town Road.” Instead, it’s a song by a 90-year-old D-Day veteran. Jim Radford wrote “Shores of Normandy” 50 years ago, in 1969, to mark the 25th anniversary of the invasion. Radford was just 15-years-old when he served as a tug boat galley boy. ABC says, “The youngest of three brothers who all served in the British Merchant Navy, Radford was able to join the war effort because tugboat companies were excepted from a Merchant Navy rule that recruits had to be at least 16 years old.”   

The song was re-released to raise money for the Normandy Memorial Trust.
