Ruggiero Leoncavallo was born on 23 aprile 1857, 153 years ago.
However he used to tell people that he was born on 8 March 1858. This was to make himself appear younger than his great rival Giacomo Puccini who was born on 22 dicembre 1858.
What a 'pagliaccio'!!
Thanks to Antonio Pisanti for this interesting factoid.
