I want to know the answer to the following question:
When was the first time Liszt and Chopin performed together?
All the background I'm provided with is that "The first, on 2 April 1833, was at a benefit concert organized by Hector Berlioz for his bankrupt Shakespearean actress wife Harriet Smithson, during which they played George Onslow's Sonata in F minor for piano duet.". Is that enough to answer the question?
