Stars are remembering Casey Kasem, the pioneering disc jockey, who died Sunday at age 82.
The former host of "America's Top 40" and the voice behind Scooby-Doo's sidekick Shaggy had suffered from a form dementia.
His family said in a statement: "Early this Father's Day morning, our dad Casey Kasem passed away surrounded by family and friends. Even though we know he is in a better place and no longer suffering, we are heartbroken. Thank you for all your love, support and prayers. The world will miss Casey Kasem, an incredible talent and humanitarian; we will miss our Dad."
Ryan Seacrest was among the celebrity friends who paid tribute to the late radio jock: "It's a sad day for the broadcasting community and for radio listeners around the world. When I was a kid, I would listen to Casey Kasem's AT40 show every weekend, and dream about someday becoming a radio DJ. So when decades later I took over his AT40 countdown show, it was a surreal moment. Casey had a distinctive friendly on-air voice, and he was just as affable and nice if you had the privilege to be in his company. He'll be greatly missed by all of us."
