Theme: Walls: Pink Floyd "The Wall", Pt 2

The second half of "The Wall" album begins with Pink, who is now almost completely isolated in "Hey You" and "Is There Anybody Out There?". Pink, trapped behind the wall, still has enough feeling to cry out and ask for help.

Hey you, out there on your own
Sitting naked by the phone
Would you touch me?
Hey you, with you ear against the wall
Waiting for someone to call out
Would you touch me?
Hey you, would you help me to carry the stone?
Open your heart, I'm coming home.

No one answers Pink's calls for help and he realizes that he is completely isolated. As per The Wall tradition, a piece of the wall moves out, becoming a small platform with a chair and a tv. Waters sits in the chair and sings "Nobody Home". 

Hidden behind the wall, Pink begins to have hallucinations of becoming a fascist dictator performing concerts at rallies with "Vera", "Bring the Boys Back Home", "Waiting for the Worms", etc. Pink puts 'undesirables' on trial, telling them to get out.

Are there any queers in the theater tonight?
Get them up against the wall!
There's one in the spotlight, he don't look right to me,
Get him up against the wall!
That one looks Jewish!
And that one's a coon!
Who let all of this riff-raff into the room?
There's one smoking a joint,
And another with spots!
If I had my way,
I'd have all of you shot!

Pink eventually puts himself on trial, and his own inner judge commands him to tear down the wall, but not before his mother, teacher, and wife have their say during "The Trial". 

 Since, my friend, you have revealed your
Deepest fear,
I sentence you to be exposed before
Your peers.
Tear down the wall!

At this point in live shows, the entire wall is torn down, revealing the band. The band plays the last song, "Outside the Wall", in all of the rubble.

 All alone, or in two's,
The ones who really love you
Walk up and down outside the wall.
Some hand in hand
And some gathered together in bands.
The bleeding hearts and artists
Make their stand.
And when they've given you their all
Some stagger and fall, after all it's not easy
Banging your heart against some mad bugger's wall.

 Listen to the album carefully, there are many tiny details in the songs, which only adds to its amazingness.
