This day in music history.

April 12, 1968, The National Academy of Recording Arts and Sciences Dinner is held in New York City. Frank Zappa and the Mothers of Invention are the entertainment. At one point during the show Frank tells the audience the event is a load of pompous hokum. He says all year long you people have manufactured this crap, now for one night you're gonna have to listen to it!" Zappa later remarks, "We played the ugliest shit we could...That's what they expected us to play."
What's the Ugliest Part of Your Body? by Frank Zappa
What's the ugliest
Part of your body?
What's the ugliest
Part of your body?
Some say your nose
Some say your toes
But I think it's
YOUR MIND
I think it's your mind,
ALL YOUR CHILDREN ARE POOR
UNFORTUNATE VICTIMS OF
SYSTEMS BEYOND THEIR
CONTROL
A PLAGUE UPON YOUR
IGNORANCE & THE GRAY
DESPAIR OF YOUR UGLY LIFE
Where did Annie go
When she went to town?
Who are all those creeps
that she brings around?
ALL YOUR CHILDREN ARE POOR
UNFORTUNATE VICTIMS OF LIES
YOU BELIEVE
A PLAGUE UPON YOUR
IGNORANCE THAT KEEPS
THE YOUNG FROM THE TRUTH
THEY DESERVE
