I explained this was a bit of fun as they are the designatory letters for members of The Magic Circle (and, yes, I am a member, indeed, I am now The Treasurer). Steve then told me that he had an unusual hobby too. He said he was a poet.
The following day I received an email from Steve containing a poem he had written for me to deliver. I loved it - but never performed it as I can't do all the tricks he references!
