"Paradise" is the only single release from Styx's 1997 live double album "Return to Paradise". The song was originally written and recorded by Dennis DeYoung for his musical "The Hunchback of Notre Dame". The song was re-recorded by Styx for inclusion as one of three new studio tracks on the live album.
Styx only wrote the song Paradise as a single.
While Paradise is the only single on that album they probably did release other singles. The system cannot determine if more singles were released beyond that album.
