This was the first of three songs the pair worked on together; the other two - "Choices" and "Wait For Me" - centred on family planning, and were endorsed by the Planned Parenthood Federation of Nigeria who used "Choices" in their PSA.Onwenu's final release on Polygram was dedicated to Winnie Mandela, the subject of a song of the same name which Onwenu performed live when Nelson Mandela and his wife visited Nigeria in 1990 following his release from prison.
