Let's sing another song, boys, this one has grown old and bitter
Ah his fingernails, I see they're broken
His ships they're all on fire
The moneylender's lovely little daughter
Ah, she's eaten, she's eaten with desire
Calls back to the song  Love Calls You By Your Name : 
 You say they  chained you to your fingernails And you climb the halls of fame 
 Practice, practice, practice! Just don’t be like Robert Schumann, the pianist who devised a finger stretching device to make himself better and ended up crippling a few fingers.
