Who's The Real Pink?

You know that Pink Floyd song Young Lust? Sure you do. Well, near the end of that tune you hear an international operator based in the US trying to place a person to person collect call to a "Mr. or Mrs Floyd" in Britian. Right? Are you with me so far?

Okay. Well, someone with a British accent answers, but hangs up on the operator. Remember? Are you following me?

All righty then. I've heard that if you play that part backwards it says "turn me on, dead man," followed by some Celtic chants and then a sort of whispering voice that intones, "she's buying a stairway to heaven".

Is that true? And furthermore, if you rearrange the letters in Pink Floyd, and then add some other letters to the mix while removing others, can you really can spell out the phrase "I buried Paul"?
