Liszt’s “Un Sospiro – Version 1” features my own “ossia cadenza 2” and is played at a moderate-ish tempo.
“Version 2” is played at slightly faster tempo and has full cadenza 2: https://www.youtube.com/watch?v=D8-xlc0yTlw
“Version 3” has full cadenza 2 and 4 extra bars after cadenza 2 which Liszt added in his own performances in later years: https://www.youtube.com/watch?v=4gsFxWAixlM
