It was over 30 years ago, I began to admire Klaus Wunderlich. I refered to him as the James Last of the organ at that time, and one of my favourites was "Raindrops keep falling on my head".
I know he used multi tracking, but I always thought this was just tremendous, with the wind and the raindrops in full stereo.
