While we anxiously await the release of Lady Gaga and Cher's duet, "The Greatest Thing" — which, according to Cher's Twitter, is supposed to drop in roughly two days — we can while away the hours with a few insider details about the song from co-writer/producer RedOne.

When MTV News caught up with the mega-producer recently, we did our best to get an early listen of the track, but no dice. Instead, we asked him to tell us specifically what kind of song "The Greatest Thing" is and whether we'll want to dance to it or sing along — or both.

"I think it's timeless. The beautiful thing about this song is, it's very uplifting, very uplifting. It's emotional, but it has dance on it, and it has a dance vibe on it," he explained. "It's just a timeless song. You can play it with the guitar, the piano, with whatever instrument you want. You can sing it a cappella, you know what I mean, it's that kind of song.

"I'm very excited about that song," Red added. "And it's an event. Cher and Lady Gaga: How big can it get?"

RedOne said Cher and Gaga were ecstatic with the finished product, and he couldn't be happier to have helped connect the two stars.

"Everybody loved it," he said. "Gaga on it, Cher, two big icons. [They are] part of music history. So it happened. I'm very happy to be a part of this."
