Sad news. First Maurice and now Robin, both still young (not to mention Andy too).
I'm a fan of early Bee Gees music. Although they are best known for their ballads and disco music, they had many great rock (psychedelic/art rock) songs at the beginning of their career. They were not only great composers and singers, but also musicians, especially Maurice.
Well, I've even written a fan fiction named after a song of theirs, written and sung by Robin, whose mood fits perfectly the story mood. I'll leave the link for the song on Youtube (I hope it is okay to link videos here) as a tribute for his talent.
Really and Sincerely
A person only sees and hears what he wants to see and hear and disregards the rest.
