"Cosmic Day" is the third track to be released from the deluxe reissue of Sign O' The Times, after "Witness 4 The Prosecution (Version 1)" and "I Could Never Take The Place Of Your Man (1979 Version)".
Prince recorded "Cosmic Day" at Sunset Sound on 15 November 1986, and it's the first time the full track has been made available.
The super deluxe edition reissue will feature 63 previously unreleased Prince tracks, alongside two full concert recordings.
