Wren sings this in Daggie's Tavern in JQS3E5.
When you're learning how to sing in the kitchen
Even though you're told it's not a Lady's Craft
Never waste your time with poetry and music
Never act without approval/ Never fraternize with staff
Never show your real motives/ Listen to the talking heads
Never reach for mommy's cheek before you go to bed
Never slum it for affection/ That's how peasants wind up dead
It starts in bright warm kitchen/ with light that's shifting gold
Warming fingers by the hearth in the kitchen
Doing just what you were always meant to do!
[When you] Sneak to midnight lessons in the Kitchen
When you skip another dinner full of bores
When you watch them pluck the lyre and the chickens
When you talk them into just one ballad more!
When you learn to use your voice in the kitchen
With the servants and the minstrel and the bard
Then you learn the truth your friends know in the kitchen:
The voice that speaks the truth can travel far
The voice that speaks the truth will travel far
