Would a lazy but combative composer have several scores to settle?

Answer 1

Yes, especially if he baroque into people's houses without a key or leaving a note (due to excessive laziness). He would soon find a long line of people ready to string him up and give him good beat down.

Answer 2

He'd Beethoven his fist on his tempo and you'd have to baton him down to stop him jumping off the clef cos he'd go Bach-ing mad before he could compose himself.
