I saw a Pink Floyd interview:
"Month Side" 30 years, there is a song that tells this song:
What is the impression of your female voice in the song "The Great Gig in The Sky"?
Finding Clare Torry (Singer) is an idea of Alan Passon. We want to add a female voice in that song, always shout. Alan has worked with him before, so we let her try again. I didn't expect her great. We gave her some encouragement and gave her some voice. "Here you have to sing quietly, here you have to sing." She sang a few times, then we spliced all the small segments into a complete singing section. It is not a record successful.
What is she like?
