The song House of Four Doors, Pt. 1 is performed by The Moody Blues .
Mystery spead it's cloak
Across the sky
We'd lost our way
Shadows fell from trees
They knew why
Then thru the leaves a light broke thru
A path lost for years lead us thru
House of four doors
I could live there forever
House of four doors
Would it be there forever?
Lonliness, the face of pilgrims eyes was known
As the door opened wide
Beauty they had found before my eyes to see
To the next door we came
Love of music showed in everything we heard
Thru the third door where are we?
Enter in all ye who seek to find within
As the plaque said on the last door
