Judas Priest

Youre in for surprise
Youre in for a shock
In london town streets
When theres darkness and fog
When you least expect me
And you turn your back
Ill attack
I smile when Im sneaking
Through shadows by the wall
I laugh when Im creeping
But you wont hear me at all
All hear my warning
Never turn your back
On the ripper
Youll soon shake with fear
Never knowing if Im near
