SOLVED: A country duet with ".... don't you, don't you"

Hi, I heard this song in supermarket once and I know it's a pretty famous classic.
What I know:

- it's a country style song
- a duet with a man and a woman (Dolly Parton maybe? Or at least Dolly Partonish)
- in the chorus she sings "...... don't you, don't you?" at the end of each sentence (something like: "you really think that ...... , don't you, don't you?)
- it's pretty old

Please help!

Maybe this country-ish cover

Susanna Hoffs - Matthew Sweet - You're so vain

The Beautiful South - A Little Time?

Thanks, BlueNileFan, but that's not it....

@wurzlsepp: That's it!!! Great! It's been bugging me for years now. I thought it would be older, but it's from 1991. Did you google it or did you just remember?

At first, i had not the slightest idea which song you could mean. But while googling i stumbled upon this song. Then i remembered

Well, thanks again for the effort.
