Ozzy Osbourne's final concert with Black Sabbath raised $190 for charity. Proceeds for the July 5 show benefited Cure Parkinson's (which Osbourne suffers from), Birmingham Children's Hospital, and Acorn Children's Hospice.

Those who were at the event or watched the livestream likely noticed that Black Sabbath drummer Bill Ward, 77, took his shirt off during the group's final performance. Now, Iommi has revealed a humorous story about Ward's habit and what the band members had to say about it.
