In page Hubert Gregg:

"

In the Second World War, he first served as a private with the Lincolnshire Regiment in 1939, before becoming an officer in the 60th Rifles the following year.[2] Gregg spoke German fluently, and worked for the BBC German service, to such good effect that Goebbels assumed he must be a German traitor.[3] He was invalided out in 1943.[2] Among his "more than 200 songs" he wrote was the wartime hit "I'm Going To Get Lit Up When The Lights Go up in London", written in 1940 and sung by his first wife, Zoe Gail, in George Black's 1943 production Strike a New Note.[2] It was broadcast in 1944 to alert the Resistance that the invasion of Europe was imminent.[2]
