The movie Saturday Night Fever came out in December of 1977 the Saturday Night Fever soundtrack was probably the turning point of the Bee Gees' career. If I Can't Have You (which became a US no. 1 hit for Yvonne Elliman), was the B-Side of Stayin' Alive.
Bee Gees singles off the soundtrack album that I remember are ...How Deep Is Your Love, Stayin' Alive , More Than a Woman and Night Fever.
For nearly a year you could't turn on a radio without hearing one of the songs from that movie. They ranked high on the charts here in the US and won awards for their work.
John Travolta was hot in the movie and tons of people tried to dance the way he did...he made it look so easy. The scary part for me looking back...my oldest son Steven was Three & a half, he'll be Forty-one in June.
