I beg to disagree! Or, at least, I prefer this:

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

The lunatic is in the hall
the lunatics are in the hall
the paper holds their folded faces to the floor
and every day the paper boy brings more

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 forbodings too
I'll see you on the dark side of the moon
The lunatic is in my head
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
there's someone in my head but it's not me

And if the cloud bursts, thunder in your ear
you shout and no one seems to hear
and if the band you're in starts playing different tunes
I'll see you on the dark side of the moon

Yet the ever relevant one seems to be this:

Of current importance, time and again...
