Doppelganger

I am often I have been told I have been seen in a location, that I have never even been to. This is explained by the fact, that quite a few people look like me!!! (poor souls) I do know that I have a double who plays keyboards, and I have affectionately introduced him as my brother at concerts ( he does some stunt doubling for me as well ,on dangerous Funerals.) However someone handed me a flyer for the forthcoming Nelson Riddle Concert. Sat on Trombone, was me!!!! only it isn't me. It could have been any other instrument like Sax or Trumpet, but no, there I am playing the old bone. Even I found this spooky. I am just wondering if I could wait outside the venue, kidnap this guy, and then slip in his seat???
