"Married Men" (also known as "(The World Is Full of) Married Men") is a song written by Dominic Bugatti and Frank Musker. It was recorded and released almost simultaneously by Welsh singer Bonnie Tyler (claimed as the original) and American Bette Midler. Due to the simultaneous release, both versions competed with each other. As a result, Tyler's version reached number 35 in the UK, while Midler's version charted in North America, including number 40 in the US Hot 100.
Tyler's version became the title theme for Robert William Young's 1979 film The World Is Full of Married Men.
