Jack Russell, the lead singer of the rock band Great White, has died at the age of 63. Russell passed away due to complications from Lewy body dementia and multiple system atrophy. He announced his retirement from touring last month following his diagnosis. Russell's career was notably marked by the tragic 2003 Station nightclub fire, which killed 100 people and injured more than 200, including band guitarist Ty Longley. Despite the controversy and legal fallout from the fire, Russell's legacy in rock music is celebrated, particularly for hits like 'Rock Me' and 'Once Bitten, Twice Shy.' He was surrounded by his family at the time of his death.
