Because of this topic, I went looking for the HBO program about the Bee Gees. I was in high school when I got my first Bee Gees album in the 60s. I sort of lost interest in the disco era (same kind of hippie guy. Had one of those Disco Sucks t-shirts). Some of the disco era music they made was still high enough caliber for me to consider it good, when heard from the distance of 2020.
I remember either reading or hearing a piece on their later collaborations with other artists that if the Bee Gees were involved, the artist was guaranteed to sell at least a million records. In terms of talent, not many achieved their level, in my opinion.
