Bill has a fully booked concert at a stadium he just arrived in the limo with his band member Tom (his twin brother) Georg (the bassists) and Gustav (the drummer) they were signing autographs as they entered so you took your chance and got a paper signed. As Bill signed your paper he looks up at you and slides his sun glasses down a bit and winked at you then pushed his sunglasses back up and finished signing the paper moving into the next fan who got something else signed.
