I want to know the answer to the following question:
For whose benefit was the first of these concerts performed for on 2 April 1833?
All the background I'm provided with is that "Their last appearance together in public was for a charity concert conducted for the Beethoven Memorial in Bonn, held at the Salle Pleyel and the Paris Conservatory on 25 and 26 April 1841.". Is that enough to answer the question?
Answer: no
