“O mio babbino caro” (“Oh My Beloved Father”) is a soprano aria from the opera Gianni Schicchi (1918), by Giacomo Puccini, The aria is frequently performed in concerts and as an encore in recitals by many popular and crossover singers; it is used in films and several bands cover the aria in their own style. The song is arguably far more well-known than the opera from which it comes.
Joshua Bell is one of the most famous violinists in the world. In an experiment initiated by The Washington Post, Bell donned a baseball cap and played as an incognito busker at the Metro subway station L’Enfant Plaza in Washington, D.C. on January 12, 2007. The experiment was videotaped on hidden camera; of the 1,097 people who passed by, only seven stopped to listen to him, and only one recognized him.
