Macbeth (opera)
Macbeth receives the guests and Lady Macbeth sings a brindisi (drinking song) which is quite similar to the famous one in La Traviata.  Macbeth is told that Banco has been murdered, but when he goes back to the table he finds Banco’s ghost sitting in his place.  He shouts and raves at the ghost.  The other people cannot see the ghost and think that Macbeth has gone mad.  The feast ends quickly.
