Anyway I sat as near as possible to him, which is difficult on a packed South West Trains carriage, but I was too near to take a picture without breaking my back, as he was behind me. So I thought, I need some evidence that it's really him. Nothing he said to his female companion helped, he was engrossed in WORD. But the first page he turned to in WORD was an article about comedian Harry Hill. Not necessarily enough evidence by itself.
Then his mobile phone went. Brill, he's bound to say something actorly. So I turned down my mp3 headphones. "You're what's known as a fad" he said to whoever was on the other end of the line. That's sort of actorly. Then not much else, asking about the person's band - sort of celebby. Then "Oh I'm not up to much today, doing a few voiceovers" - Bingo, who else would say something like that?
So we got to Waterloo station and him and female partner hung behind, clearly not in a rush like the rest of us. Was I sad enough to wait around to see where he got off and possibly blag a picture. No, I decided I wasn't.
Anyway, at Waterloo Underground station I was standing on the Bakerloo line platform heading for Piccadilly Circus. Who should turn up a few people down from me, still with his copy of WORD magazine - Rob Bloody Brydon. As Harry Hill himself would say "What are the chances of that happening?".
We got onto a fairly empty carriage. I sort of had a chance to sit opposite him. Again, too close, too obvious for a photo opportunity. So I sat diagonally behind and managed to get some shots of the side of his head reading WORD.
He got off at Piccadilly Circus, so what more proof did I need - Piccadilly Circus, home of theatre luvvies, also where my Dr Who Peter Davison celeb spot departed and Golden Square, just round the corner, is home of loads of people who make TV and radio commercials, where he may have been heading for his voiceover. Indeed at work, we've walked past Kevin Spacey making mobile phone calls in our office stairwell - our "studios" at Archer Street are the home to lots of little arty/meedja/production/webby/pilates/architect type outfits.
He chose the stairs to leave the platform level. Stalking ended at that point - nothing but broken escalators will make me face the ricketty, vertigo inducing, head spinning, spiral staircase at Piccadilly Circus, particularly not on Friday 13th.
