Spike Lee’s new movie, BlacKkKlansman is set to finish with an unreleased Prince song.

In a new interview with Rolling Stone, Lee revealed that the film’s end credits will also have Prince’s cover of “Mary Don’t You Weep.”

Lee further explained how he managed to get the song in the film.

“I knew that I needed an end-credits song. I’ve become very close with Troy Carter, one of the executives at Spotify [and a Prince estate advisor]. So I invited Troy to a private screening. And after, he said, ‘Spike, I got the song.’ And that was ‘Mary Don’t You Weep,’ which had been recorded on cassette in the mid-Eighties,” Lee said. “Prince wanted me to have that song, I don’t care what nobody says. My brother Prince wanted me to have that song. For this film. There’s no other explanation to me. This cassette is in the back of the vaults. In Paisley Park. And all of a sudden, out of nowhere, it’s discovered? Nah-ah. That ain’t an accident.”

It became recently known that the Prince estate was sorting through “as many as 1,000” unheard songs for the making of new albums.
