Jermaine first heard Theresa Rhodes sing "Save Tomorrow" in 1993. He liked the song and its message and offered to sing it with her. The duet was first performed in public at a charity concert in England where Theresa appeared as Jermaine's guest artist. The song was recorded in Geneva, at Dinemec Studio, in December 1994. It was produced by Matt Clifford who had previously worked with Mick Jagger and toured with the Rolling Stones in 1992. The single was released in Europe in 1995. Jermaine and Theresa toured Germany to promote the single. They appeared on 13 television shows and were interviewed on 12 radio stations. The song climbed to number 8 on the Radio Berlin Charts. A video was made in the 90’s showing Jermaine and Theresa working together in the recording studio and it was assembled with Red Cross images of the war in Sarajevo as well as footage showing the Rwanda exodus following the genocide in that country. The video was deemed “too sad” to go public so little use was made of it during the promotion tour in Germany that followed and it was finally shelved. In 2015 The YouTube channel of Theresa Rhodes finally published the "lost" music video.
