When I found out that Tony was doing some interviews with Mark Lewisohn I ran round all the record stalls at the convention to see if could find a TS and the Beatles LP - which I did manage to find in the end!
Tony was actually a great guy - incredibly friendly, happy to sign FREE autographs and pose for pics! He signed my LP and your pic and was genuinely interested in your forum. Unfortunately there was a massive crowd queueing for his sig so I had to get out of the way fairly quickly - so I shook his hand and wished him well with his band and the tour.
Perhaps you could email a copy of the pic to him and explain some more about your forum - I'm sure he's bound to remember signing the pic as it was probably the memorable thing he signed that day!!!
