Black Sabbath singer Ozzy Osbourne's sisters recall their final interactions before his death at 76, noting he was frail but still joking before a farewell performance in England.

Ozzy Osbourne was at home amid the things he loves most in the days leading up to his death, a source tells PEOPLE. Osbourne, 76, died on Tuesday, July 22, with his family, including wife Sharon, by his side.
