Analysis of information sources in references of the Wikipedia article "Laurel and Hardy" in English language version.
Hardy, who was known for his hearty appetite, burned himself while cooking a leg of lamb, so badly that he couldn't finish a film he was working on with McCarey, who asked Laurel, who at the time was working as a gag writer at the studio, to step in.
He was cooking a leg of lamb when some scalding gravy splashed on his arm, taking him out of commission.
Though it is one of those songs that seems to have always been around, like "Happy Birthday" or "Auld Lang Syne", it was actually written in 1928 by Thomas Marvin Hatley. Born in Reed, Oklahoma on April 3, 1905, Hatley could play almost any musical instrument by the time he entered his late teens. While attending UCLA in California, Hatley found work at KFVD, a radio station located on the Hal Roach Studios lot. He wrote the simple and endearing "Ku-Ku" as a radio time signal.
