Johnny Depp made a surprise appearance alongside Alice Cooper to pay tribute to Ozzy Osbourne at a concert on Friday night, days after the rock icon's death.

Ozzy Osbourne, who died July 22 at the age of 76, was known as the singer of influential heavy metal band Black Sabbath and for his outrageous solo career that earned him the title the Prince of Darkness. Yet Ozzy also had a softer side. He was a huge fan of the Beatles.
