Something of an unlikely one.
On April 9, 2004, “Weird” Al Yankovic was scheduled to perform a concert in Appleton, Wisconsin, in support of his album Poodle Hat. Hours before showtime, he received a call from his wife telling him that both his mother and his father were dead, victims of accidental carbon monoxide poisoning.
Yankovic went on with the show, saying, “Since my music had helped many of my fans through tough times, maybe it would work for me as well”. He also said that it would “at least give me a break from sobbing all the time.”
Later, he said, “If I didn’t have anything to distract me, I probably would have spiraled into an even deeper depression. For a couple of hours each night, I could go on stage and put on a big fake smile and pretend like everything was just okay.”
Ten years later, he said their death was “the worst thing that ever happened to me.” He said, “I knew intellectually, that at some point, probably, I’d have to, you know, live through the death of my parents, but I never thought it would be at the same time, and so abruptly.”
