Dolly Parton discusses her 'dirt poor' beginnings and 'hard-working' dad in new documentary.

Dolly Parton claims that although her song about working from 9 to 5 has made millions of dollars, her father, a tobacco farmer, would have hardly had time for it.

The 77-year-old icon of country music claims that Robert Lee, who got up at 4 a.m. to labor in Tennessee, is the source of her strong work ethic.

"I like to work; that's just like my dad," she declares. If I have a purpose for performing the labor, it's never too long or too hard.

Dolly has reaped the rewards, as seen by her over 100 million album sales, 110 charting singles, 25 No. 1 hits, and more over 3,000 written songs. 

Her 49th solo album, Rockstar, debuted at No. 3 on the Billboard list, making it her highest-charting LP ever. She shows no signs of slowing down.

Dolly was one of Robert Lee and his wife Avie's twelve children. The family was "dirt poor," according to Dolly. However, she enjoyed getting up early to spend time with her father.

"I used to let Mama sleep in and get up with Daddy to pack his lunch. Daddy and I would talk, and I felt that those were priceless hours," she explains.

My father was an industrious laborer who put in long hours, working from sunrise to sunset. Daddy was required to rise at four o'clock.
