I went to college as a musical theatre major (yes, that exists) not knowing who Stephen Sondheim was.
I was quickly "schooled" by my more versed (literally) peers.
How foolish I was!
I've been coveting this book since publication:
Finishing the Hat: Stephen Sondheim (Author)Finishing the Hat: Collected Lyrics (1954-1981) with Attendant Comments, Principles, Heresies, Grudges, Whines and Anecdotes
Now it's all mine. Time to expand my knowledge. Freshman LuRuSo would be so proud. So would Paul Simon: New York Times Book Review
