Dolly Parton has released some incredible songs over the years, many of which have shaped her career and the culture of country music.

But her 1974 song "I Will Always Love You" is perhaps her greatest song ever written. And she originally wrote it for entertainment host Porter Wagoner,

who was born around this time—August 12—in 1927. In the early 1970s, Dolly was recruited as the main entertainment on Porter's TV show.

The Porter Wagoner Show starred Dolly for seven years, from 1967 to 1974, when her tenure catapulted her career to stratospheric success.

But the day came when she decided that she had to leave the show. Dolly looked back and remembered, "Well, five years passed and I was still on the show.

We had big hit duets. It was his show and I understood all that, but I still wanted to go.So I finally thought, 'How can I make him understand how much I appreciate everything,

but that I have to go? He won't listen to me. He won't listen to reason when I want to go!' (sic) "So I went home," continued Dolly.

"And I thought, 'Well, what do you do best? You write songs.' So I sat down and wrote this song [I Will Always Love You]."
