During the 1975-1979 period, The Bee Gees pretty much ruled radio. Especially in 1978. You could not get away from them. They even wrote massive hit songs for other artists such as Yvonne Elliman and Tavares. And the Andy Gibb hits were pretty much Bee Gees songs.
Believe it or not, these are the same Bee Gees:
New York Mining Disaster, 1941 (1967)
Holiday (1967)
Massachusetts (1967)
