And your challenge is
According to this page, I went to a Proms concert on 4 August 1995, and saw Simon Rattle conduct Beethoven’s Eroica symphony. The challenge is to find out what other pieces were part of the programme that evening.
As I write, I have no idea what the answer is. My diary might tell me, and I will consult it later today, but the web seems to be of no help whatsoever. Kudos to the first link to a web-page with the relevant information.
