What is said right before 'Empty Spaces?'
Reprinted from the Echoes FAQ
The soft gibberish you can hear in the background here is a backwards
message. When you play it backwards, you hear:
"Congratulations. You have just discovered the secret message.
Please send your answer to Old Pink, care of the Funny Farm, Chalfont"
and, in the background, after that, even softer:
"Roger, Carolyn's on the phone!" "Okay."
