"Black Velvet Band" is the title of a traditional Irish song sung by Grace Burgess in Episode 1.2, to Thomas Shelby at The Garrison Pub. The lyrics are as follows:
“In a neat little town they call Belfast
Apprentice to trade I was bound
Many an hour’s sweet happiness
Had I spent in that neat little town
A sad misfortune came over me
Which caused me to stray from the land
Far away from my friends and relations
Betrayed by the black velvet band.
Her eyes, they shone like diamonds
I thought her the queen of the land
And her hair, it hung over her shoulder
Tied up with a black velvet band.”
