Kenny Rogers and Dolly Parton are two of the most legendary voices in country music, and they also have a long-standing friendship. The two singers have teamed up for a new duet, 'You Can't Make Old Friends,' also releasing a music video that celebrates their relationship in a very special way.

Rogers describes the duet as being touching, sad, and wonderful -- and we would agree. Its poignant lyrics are slightly sad, but overall, it's extremely touching and completely wonderful.

The video begins in black and white, with Rogers and Parton reminiscing together about their first moments as singing buddies. It may be one of the sweetest things we've seen in a very long time. "It's been 30 years since 'Islands in the Stream' was a hit," explains Parton, adding, "To this day, I never get tired of hearing that song."

After the reminiscing, the viewer sees Rogers standing alone onstage, singing to an empty auditorium, and Parton singing a verse alone in her dressing room. It's interspersed with footage of the two performing together over the years, and it's heartwarming to see that while the singers and their styles (and haircuts!) have evolved, their friendship has stayed steady.

Rogers says sentimentally, "Out of everybody in the business, she is my best friend." Parton echoes his thoughts, saying, sweetly, "Yeah! I feel the same way."

Eventually, while Rogers is performing onstage, his eyes light up -- Parton walks up and sings with him, harmonizing beautifully. The music video features several sweet interviews with the pair, talking about what 'You Can't Make Old Friends' means to them and their gratitude for the long-lasting friendship they've formed.

"I think when we made 'Islands in the Stream,' we connected musically," Rogers says. "When we made 'You Can't Make Old Friends,' we connected personally." He adds, "For me, it's not important that this is a hit song, but it's important historically to have it on tape."

Not only was it a thrill for the best friends to work together, it's also a huge thrill for country music fans, young and old, who have been influenced by their music.
