I am performing K466 soon... I will do the Beethoven cadenza to the 1st movement (conductor's request - and I also think it's the best one). For the third movement, I plan to play my own eingang at the fermata, but I haven't quite decided on a cadenza. I will definitely default to Beethoven there too, unless something else happens. I love Barenboim's cadenza, but can't get my hands on it. I defintiely don't want the Hummel cadenza there, because I don't like it. Does anyone have pdf's of any of the other cadenzas? Possibly the Brahms?
