Eternity is the first track on Sheena Easton’s eighth album No Sound But A Heart, and released as its first and only single. In 1993, it was included as the 19th and final track on The World Of Sheena Easton: The Singles Collection compilation. The song was written, produced and largely recorded by Prince (although production is credited to David Leonard, and Prince uses the pseudonyms Rocker Happyfeller and Freddie "The Phantom" for musician credits).
Basic tracking took place in December 1985 at Sunset Soundin Hollywood, California. Together with Euphoria Highway the song was first offered to Vanessa Williams (with George Clinton producing), but she never ended up signing a record deal for the proposed project, so never recorded it. The song may or may not have also been considered for Jill Jones.
Sheena Easton’s vocals were recorded at a later session, likely in a different studio and without Prince, although details of her recording are not known.
in 1988 Chaka Khan included a version of Eternity on her eighth album CK. Although Prince contributed to the album (on the track Sticky Wicked), he did not contribute to this track; it is considered a cover version, therefore, and is not discussed in detail here.
