I've only just noticed this thread, but I feel compelled to say my bit.
I echo all the above sentiments - what a sad loss he is.
Pink Floyd have been my favourite band since I first heard "Shine on you crazy diamond" as a 14 year-old boy in 1978.
I spent all of my available paper-round money collecting everything of theirs I could
get my hands on, and bought "The Wall" on the day it was released.
I was also lucky enough to see the original live show in 1980... what a fantastic experience that was!
Richard Wright should be a true inspiration to anyone who sits down at a keyboard.
His subtle, ambient, sounds and his ability to pare back all the
unneccessary 'wizardry', especially prevalent in the grandiose 1970's, made the
'Pink Floyd sound' one that has remained a major influence in my
approach to keyboard playing and will continue to do so.
Rest In Peace, Richard and thank you.
