The family of rock legend David Bowie, who died Sunday at 69 after a largely secret battle with cancer, thanked his fans while asking for their privacy to be respected in a Facebook post Thursday. "We are overwhelmed by and grateful for the love and support shown throughout the world," they write. The family says it's organizing a "private ceremony" to remember Bowie, though that doesn't mean his fans shouldn't remember him in their own way. "It is important to note that while the concerts and tributes planned for the coming weeks are all welcome, none are official memorials organized or endorsed by the family," the post states. "Just as each and every one of us found something unique in David's music, we welcome everyone’s celebration of his life as they see fit." (More David Bowie stories.)
