[Verse 1]
25 years and my life is still
Tryin' to get up that great big hill of hope
For a destination
I realized quickly when I knew I should
That the world was made up of this brotherhood of man
For whatever that means

[Pre-Chorus]
And so I cry sometimes when I'm lying in bed
Just to get it all out what's in my head
And I, I am feeling a little peculiar
And so I wake in the morning and I step outside
And I take a deep breath and I get real high
And I scream from the top of my lungs
"What's going on?"

[Chorus]
And I say, hey-ey-ey
Hey-ey-ey
I said "Hey, a-what's going on?"
And I say, hey-ey-ey
Hey-ey-ey
I said "Hey, a-what's going on?"

Verse 1: Roger Waters]
The lunatic is on the grass
The lunatic is on the grass
Remembering games and daisy chains and laughs
Got to keep the loonies on the path

[Verse 2: Roger Waters]
The lunatic is in the hall
The lunatics are in my hall
The paper holds their folded faces to the floor
And every day the paperboy brings more

[Chorus: Roger Waters]
And if the dam breaks open many years too soon
And if there is no room upon the hill
And if your head explodes with dark forebodings too
I'll see you on the dark side of the moon

[Verse 3: Roger Waters & Peter Watts]
The lunatic is in my head (*laughter*)
The lunatic is in my head
You raise the blade, you make the change
You rearrange me 'till I'm sane
You lock the door and throw away the key
And there's someone in my head, but it's not me

The Fugs
en.wikipedia.org

... The Fugs are an American rock band formed in New York City in late 1964,[2] by the poets Ed Sanders and Tuli Kupferberg, with Ken Weaver on drums. Soon afterward, they were joined by Peter Stampfel and Steve Weber of the Holy Modal Rounders. Kupferberg named the band from a euphemism for ---- used in Norman Mailer's novel The Naked and the Dead.

The band was one of the leaders of the underground scene of the 1960s and became an important part of the American counterculture of that decade.[3] The group is known for its comedic, even lewd, nature but also earned fame through its persistent anti-Vietnam War sentiment during the 1960s.[2]

A famous song of theirs was "Kill for Peace",[4] on their 1966 album The Fugs.

Some 1969 correspondence, found inside an FBI file on the rock group the Doors, called the Fugs the "most vulgar thing the human mind could possibly conceive".[5]

They have been derided for their scatological lyrics.[6] But, Tom Robbins wrote of them in 1968, "Incongruously ... this trio of hairy gross ginch gropers is the most intellectual, sophisticated and literary ensemble in rock."[7] The Fugs have been labeled avant-rock noise music.[8] ...

Yup, the Fugs.
