Are / were you hitherto aware
a) the name of the composer?
b) the name of the *thing* (avoiding spoiler there) for which it was written?
c) a vague outline of the plot of the said *thing*?
Based on the blank looks I got at work when I used the *thing* as an analogy for something I am guessing this isn't as well known as I thought, or maybe that's just my colleagues.
