Speaking of singers doing acting jobs, here's another one for you. We bet you didn't know that Johnny Cash made a cameo in The Simpsons. Fans will remember the episode where Homer hallucinates after eating a ridiculously hot chili at a chili fair. Whilst hallucinating he meets his spirit guide in the desert, also known as the Space Coyote. Homer refers to him as Wolfy.
Like Sting, Johnny Cash wasn't just a singer-songwriter either. He was a guitarist, actor, and author, too. Though most of us already knew about his acting career after seeing him onscreen in Five Minutes to Live, The Road to Nashville, A Gunfight, and The Hunted. At the end of the day, we probably do prefer him as a singer, but we will never forget him as The Space Coyote, or 'Wolfy'.
