In a new extended trailer for BlacKkKlansman, hear Prince's cover of classic gospel track 'Mary Don't You Weep'.

The track has been covered by other acclaimed musicians including Aretha Franklin and Bruce Springsteen. However, Prince puts his own soul spin on the tune.

Just a simple drum beat, a stirring jazz piano melody and Prince's falsetto vocals - it sounds like a soul classic, perfect for a movie such as BlacKkKlansman which celebrates black culture. Hear it below.

As well as being included in BlacKkKlansman's soundtrack, the song will also feature on Piano and a Microphone 1983, a posthumous album from Prince who died in 2016.

The collection of songs was discovered in Prince's 'Vault' at Paisley Park as a single cassette tape. The music was recorded in one take at his Kiowa Trail home studio in Chanhassen, Minnesota.

Piano and a Microphone 1983 will be released September 21.
