Well today I saw Matthew Kelly out of "Tonight Matthew, I'm going to be" - top Saturday ITV programme Stars in their Eyes. Now I know that Matthew lives near me as a couple of years ago I did see him myself at Turnham Green tube station. He also rather bizarrely gave me his autograph when I went up to him with a notebook at some function when I was simply trying to ask him a question.
Since leaving Stars in their Eyes Matthew, has gone on to get rave reviews by playing Lennie in Of Mice & Men at the Savoy Theatre in London. Amazingly I did manage to get a picture of Matthew at Gunnersbury tube station today and believe it or not that's him leaning against the poster of Lesley Joseph. See Matthew at Gunnersbury & Matthew as Lennie side by side.
So he wasn't exactly on the tube. But I was when I saw him, so I think that counts.
