I want to know the answer to the following question:
What event were Chopin and Sand at on 26 July 1840?
All the background I'm provided with is that "At the funeral of the tenor Adolphe Nourrit in Paris in 1839, Chopin made a rare appearance at the organ, playing a transcription of Franz Schubert's lied Die Gestirne.". Is that enough to answer the question?
