On Dec. 24, 1977, “How Deep Is Your Love” by the Bee Gees topped the Billboard Hot 100 and reigned at #1 for three weeks.
Barry Gibbs and his younger twin brothers, Robin and Maurice, had begun singing and performing as children in England before the family moved to Australia in 1958. The Brothers Gibb continued performing and recording Down Under and became international stars with a string of hits starting in the late ’60s.
“How Deep Is Your Love” was written for singer Yvonne Elliman (Mary Magdalene in the original cast of the rock opera Jesus Christ Superstar and backup vocalist on Clapton’s cover of “I Shot the Sheriff”), but longtime friend and producer Robert Stigwood asked the Brothers Gibb to record the song themselves for a motion picture he was producing based on a magazine article by Nik Cohn, “Tribal Rites of the New Saturday Night.”
The song was one of six the Bee Gees contributed to the film’s soundtrack, Saturday Night Fever, which went on to become the best selling movie soundtrack LP in history.
The single became the first of six consecutive #1 hits for the Bee Gees (the only other group to have done this was the Beatles), and the song set a record for staying in the Top 10 for 17 weeks. At the 20th Grammy Awards in 1978, “How Deep is Your Love” won Best Pop Performance by a Group.
