I know one but not closely, my sister know him better and he visits her best friend several times a week. Theyve known each other for years. My sister knows quite a few actually but he's by far the most famous.
Quite a popular male singer, HUGE in his day, he still fills arenas. Nice guy, I went to college with his daughter.
Not going to say who he is though cuz ill get PM's for autographs ect, ive got them before for people and now its embarrasing. Besides, if his daughter reads this its like im pimping him out haha.
