Mercyful Fate - On A Night Of Full Moon

They're walking by the night
The moon has frozen blue
Long black coats a shelter for the rain
Their load must get through

Now bats are leaving their trees
They're joining the call
Seven satanic Hell preachers
Heading for the hall

Bringing the blood of a newborn child
Got to succeed, if not it's Satan's fall

Home... Come home
Evil messengers with blood stained wings
Home... Come home
Home... Come home

Is it Satan's fall?
