Welcome back my friends to the show that never ends...

We're so glad you could attend
Come inside! Come inside!

There behind a glass is a real blade of grass
be careful as you pass.
Move along! Move along!

Come inside, the show's about to start
guaranteed to blow your head apart

Rest assured you'll get your money's worth
The greatest show in Heaven, Hell or Earth.
You've got to see the show, it's a dynamo.
You've got to see the show, it's rock and roll ...

Right before your eyes we pull laughter from the skies
And he laughs until he cries
then he dies then he dies

Come inside the shows about to start
Guaranteed to blow your head apart
You gotta see the show
It's a dynamo
You gotta see the show
It's rock and roll
