The band was fronted by session vocalist Christian James (born 21 December 1962) and included Ray St. John as guitarist and songwriter, formerly of Latin soul band Pride, and Neil Palmer on the keyboard, formerly a member of the short-lived synth-rock act Atomage and dance duo Two People.
Released at Christmas in 1989, the song became a major success all over Europe, bringing the band to international audiences.
During work on their second album, Epic Records were taken over by Sony, and due to various structuring and personnel changes within the company Halo James could not fulfil their earlier success.
St. John, who had previously co-written Sade's 1984 hit "Smooth Operator" prior to forming Halo James, still remains active as a songwriter, and has written hit songs for several other worldwide artists, including Snoop Dogg and Gabrielle.
Palmer worked with Melanie between 1996 and 2001, and with Haddaway between 2002 and 2003; in 2004 he started a popular music shop in London called Rockbottom, but this closed in 2011.
