I have attempted in the past to get in-person autographs but have never had any success. me and my brother are taking a trip to London the beginning of June 2019. I was wondering if anyone could offer advice on how to go about trying to get Paul McCartney's autograph wow in the UK. Like maybe places that might be having events he would be attending. What place is the key is frequently seen. Also I would like advice on how to go about approaching him for an autograph if I do see him. Thanks look forward to all replies.
