Jesus fuck, this theory makes way more sense than it should. Look at the lyrics to A Trick of the Tail:
Bored of the life on the city of gold
He'd left and let nobody know.
Gone were the towers he had known from a child,
Alone with the dream of a life
He travelled the wide open road,
The blinkered arcade,
In search of another to share in his life.
Nowhere.
Everyone looked so strange to him.
They've got no horns and they've got no tail
They don't even know of our existence.
Am I wrong to believe in a city of gold
That lies in the deep distance, he cried and wept
