You're welcome. He's actually a professional magician. Lots of videos of him on youtube. I've seen his stuff over the last few years there.
He does look like Fin, though, doesn't he?
The trick he does is a simple one, though. Wouldn't fool a magician, like Penn and Teller. The first part where he guessed the guy was thinking of the ace of spades was a 1 in 52 chance. In other videos, he says, "I've not only found your card but I've changed it into the ace of spades!" It was supposed to be a joke -- he got lucky -- and on TV! Or the celebrity judge was a stooge. (Not Moe, Larry, or Curly, but meaning he was in on it.)
Go to 2:30.
Here's the other trick he did on that TV show above -- but when he was much younger. You'll see kinda how he gets the spectator to "choose" the right card of the 5 on the table. (After he controlled it and made it look like all of the cards were wrong.) Again, he got very lucky on that TV show above. Either that or they edited it to make it look like the first card she pointed to was correct. I kinda detected an edit.
Got to 8:18
I've been a magic hobbyist for over 50 years myself. Started when I was a kid.
Anyway, Mark Lewis is a very experienced professional magician, and the routine he did on TV, he's been doing for many, many years. And now he looks just like Jimmy Finlayson!
