The "Die Hard" actor had done a successful cover version of famous song "Under the boardwalk" in the late 1980's. The track, which was originally sung by The Drifters in 1964, made Willis reach number two positions in Britain's singles countdown.
The 58-year-old also sung his version of soul classic "Respect Yourself", but now cannot hear himself singing, reports femalefirst.com.
"I shout in key. There are a lot of really good singers in the world and I'm very happy to let them handle that. I just can't stand there and stand the sound of my own voice. It's excruciating," Yorkshire Post quoted Willis as saying.
