Summarise a Choir's Term of Rehearsal Notes Into a Concert Programme Note

The conductor has a term's worth of scrawled rehearsal notes and the concert programme is due at the printer tomorrow. This sorts which pieces are genuinely ready, pulls out the one anecdote worth sharing, and drafts a warm, non-technical programme note, so the audience gets more than a bare list of titles.

**Summarise the notes into a printable programme note:**
1. Identify which pieces the notes describe as genuinely ready to perform against those still shaky
2. Pull out any interesting rehearsal anecdotes or context worth sharing with an audience, such as why a piece was chosen or a challenge overcome
3. Draft a programme note of roughly 150 words covering the pieces and one piece of context, written for a general audience with no musical training
