Country music legend Dolly Parton has said that she started writing her iconic track 9 to 5 on her nails as she was bored on the set of the film of the same name.
The 74-year-old singing sensation revealed how she created the catchy beat during downtime between takes of the much-loved 1980 comedy about women in the workplace, which also starred Jane Fonda and Lily Tomlin.
The thirteen-time Grammy winner said the clacking heard at the beginning of the track is credited as 'Nails by Dolly' on the soundtrack album.
Speaking to People magazine, she said: "The thing I hate about the movies is all the waiting around time."
"I realised on the set of 9 to 5 in 1979 that I had to do something besides just sitting there. I couldn't play my guitar - I didn't want to disrupt everything on the set by making music," she said.
"So I would just click my nails, making them sound like a typewriter. Then I used that sound as my music."
"I started writing 9 to 5 on the set of the movie that way," Parton continued. "I'd go back to my hotel every night and put down what I had written that day, playing my guitar and getting it on tape.
"Over a long period of time, I wrote the song on my nails."
