Lyrics of Dr.watson, i presume

I sat in a motel room with the doctor
Just before we were supposed to sing
He said regarding this guardian wing
This black and clipped misshapen thing
Hobbling on from claw to ring
Hung upside down and cawing
Pecking at carrion of the fallen
Battalion
Thawing
On frozen mooring

Blackbird in a crust no more
They fell down 4 and 20
Bloodstained the land of want and plenty
Now raven standing at his shoulder
Stared with eyes of molten solder

Dripping on a lacquer box
Introducing keys to locks
Seven talents there where hidden
Mysterious and some forbidden

Take the honey from the comb
Ravel thread around the loom
Dig the dirt up from the tomb
Dr. watson, i presume

One will follow
Two unknown sorrow
Three for laughter
Four ever after
Five-foot flood when the waters hit
Six feet deep, the eternal pit

Seven prayers and seven pleas
To eight imagined deities
Cat o' nine tails
Cat of nine lives
Brides turned into old wives tales
Your complexion colours then it pales
And into the sunset it sails

Soon these secrets will be scattered
Heaven knows what lies inside
It took a moment to discover
A lifetime to decide

Take the honey from the comb
Ravel thread around the loom
Dig the dirt up from the tomb
Dr. watson, i presume
