There's Only Three Kinds of Rock

Original Song: "There's Only One Way To Rock" by Sammy Hagar

Now insects have a lot of names
All over the world, 'cause they're not the same
And there's so many types [of] alcohol
A million brands and I drink them all

But there's only three kinds
There's only three kinds of rock

And there are things up in the sky
Like birds and clouds and planes and ballons and even pie
But if you analyze this crusty planet
There's lots of rock, but don't take it for granite

Because there's three kinds
You know there's three kinds of rock
Keep this in your mind
There's one-two-three kinds of rock

Now quickly, check this chip off the block
Could it be flint, could it be chalk

When you're stoned you're one of us
Metamorphic 1, 2 igneous
And 3 sedimentary
If you learn about petrology

There's only three kinds
There's only three kinds of rock
For all of mankind
There's only three kinds of rock

Check out this quartz, check out this slate
Check out this limestone, ain't it great

There's only three kinds
There's only three kinds of rock
From all that you find
There's only three kinds of rock
If you are inclined
You should go watch "What's Up, Doc?"*

Surface or strip mined
When it is defined
There's only three kinds of rock
Yeah, of rock
(Rock on!)
Around the clock
