Deep Purple Knocking At Your Back Door

Sweet Lucy was a dancer
But none of us would chance her
Because she was a Samurai
She made electric shadows
Beyond our fingertips
And none of us could reach that high
She came on like a teaser
I had to touch and please her
Enjoy a little paradise
The log was in my pocket
When Lucy met the Rockett
And she never knew the reason why
I can't deny it
With that smile on her face
It's not the kill
It's the thrill of the chase
Feel it coming
It's knocking at the door
