Met him today (properly, not just a hi)
A friend found his wallet on the Heath so we took it round to his house. He wasn't in at first, but I left a note and he phoned us 10 minutes after he'd left. Since the guy with the wallet had already cycled off, we phoned him and waited in Graham's for him to come back.
Graham seemed like a really genuine nice guy. He was really pleased we'd found the wallet as it had pictures of his daughter in it that he had no copies of. We hung out in his living room for about half an hour, and he spent 10 minutes looking around his house for various stuff to give us. In total we got 3 (signed) limted edition vinyls, 3 singles and 2 albums, plus all the money in his wallet.
He seemed like a really top bloke if any Blur fans are interested. He wasn't a standard thanks-now-please-leave celebrity type. He was dissapointed he didn't have more money in his wallet (although he had quite a bit) to give us and introduced us to his daughter and nanny. Also, before he left he took our mates address as he lived nearby and said he would drop off some more stuff in the future.
