Empty Spaces (The Wall Work In Progress, Pt. 2, 1979) [Programme 3] [Band Demo] - 2011 Remastered Version

"Congratulations, You have just discovered the secret message.
Please send your answer to 'Old Pink',
Care of the funny farm, Chalfont..." - Spoken By Roger

"Roger, Caroline's on the phone..." - Unknown Voice

What shall we use
To fill the empty spaces
Where we used to talk?
How shall I fill
The final places?
How should I complete the wall
