Susan's Lungs

Anyone ever heard of this song? I downloaded it and it claims to be a Pink Floyd song. I've only got the first 45 seconds after which it abruptly cuts of making me think there's much more to the song. It features a woman speaking in what sounds like French over the music and is fairly pleasant.

Just wondering if anyone had ever heard of this, and if it's legit in its claim.

Never heard of it. But I wouldn't call myself an authority in the early stuff.
