The Red Rocker's official website tells fans that the book consists of many different celebrities wearing a pair of Elvis' personally owned famous sunglasses.

Aneruos & Priscilla reached out to Hagar because they really wanted him to be a part of this very special tribute and knew "he would look pretty cool with Elvis' glasses on."

Apart from Hagar the book will feature Robert Plant, Steven Tyler, Willie Nelson, Sam Elliot, Johnny Depp, Elton John, Peter Fonda, Tony Hawk, and more.
