i have the Black Lab CD, and I thought it was "sheet" not "shield".... little late on this mary, that promo has been out since November.
Edit:
Chorus Lyrics to This Night by Black Lab
so take this night and wrap it around me like a sheet.
I know I’m not forgiven but I need a place to sleep.
so take this night and lay me down on the street.
I know I’m not forgiven but I hope that I’ll be given some sleep.
