Hear Prince's Piano Demo of "17 Days"

Hear Prince's Piano Demo of '17 Days'
Though Prince's estate is currently looking to sue some prolific bootleggers, an official posthumous release is set to arrive later this month with Piano & a Microphone: 1983

A second track from the forthcoming release has now been shared, and it's a solo piano version of "17 Days." The song is known as the B-side to "When Doves Cry," from 1984's Purple Rain.

You can hear the demo in the player below.

The song follows the release of "Mary Don't You Weep," which arrived alongside a Spike Lee-directed music video.
