We've all surely sang the epic, romantic chorus of 'I Will Always Love You' to a loved one of ours.

's heartbreaking ballad was a major hit upon its original release in 1974, and has remained a favourite sing-a-long for lovers ever since.

Even  supposedly sang it to his ex-wife  as they both walked down the steps of the divorce courthouse hand-in-hand following their divorce.

Priscilla shared that moment with Dolly personally, which really touched her.

What deeply flattered Dolly even more so, however, was when Elvis showed his interest in covering her ode to undying love.

But as events turned out it wouldn't ever materialise, as Dolly "cried all night" after having to reject the proposition.

Recently talking to  with Reba McEntire, Dolly recalled that: “I was so excited, I told everybody.

"They had called me that Elvis was recording it, and if I wanted to come to the studio. Elvis wanted to meet me and all that."

It was Presley's manager  that approached Dolly about the potential recording, and her excitement was quickly dampened.

“'You know, we don’t record anything with Elvis unless we have the publishing, or at least half the publishing'” the Colonel told Dolly.

She remembers replying to him saying: "Well, that throws a new light on this because I can’t give you half the publishing. I’m gonna leave that to my family. I can’t do that.”

There and then, the opportunity for her song to be sung by The King Of Rock 'n' Roll was quashed, given the Colonel's infamous temperament and uncompromising nature.

Dolly stuck to her guns by refusing the terms and choosing not to miss out on possible millions in royalties, but immediately burst into tears.

"I cried all night. Oh, I just pictured Elvis, like, singing it." Dolly sighed. "And I know that Elvis loved it. And I know it wasn’t him, but it’s true. I said no.”

It a decision that defined Dolly's career, being strong and believing in her music. Though she had always wondered 'what if', and how '' would've sounded had Elvis covered it.

She previously shared with CMT that: "I always wondered what it would sound like. I know he’d kill it. Don’t you? He would have killed it."

Her conviction in her own song would eventually pay off as we all know however, when  would cover Dolly's ballad for the 1992 romantic drama , after  apparently suggested it.
