"To mark the first anniversary of me playing the Super Mario Bros. Theme Tune during a church service, I decided that this year I would play the Tetris theme.

As is customary in my church, the concluding voluntary was written down in the service booklet, which I wrote down as "Tetris Theme Tune". I don't think anyone got mad, and I was booked to play a carol service pretty soon after playing the piece - so I lived to play another day.

Enjoy."
