Couldn't believe my eyes

I did not see either the Queen Mother or Elvis on Sunday. I was joking. It begins to appear that my imagined sighting of James Macmillan was due to something more than an overactive imagination because, as I learned this morning, he was due to conduct his St John Passion at the Philharmonic this evening. So either I did see him or something very spooky happened! "The greatest living Scottish Catholic composer!", my son remarked. "Quite possibly the greatest living Scottish composer," I replied,. "Ever!" I added, realising that I knew of no other composer from Scotland.
Now I just hope that my stare was not too obvious!
