Yesterday morning, there I was in the bathroom with Radio 3 playing one minute and the next, I was back at school.  More accurately, I was standing in morning assembly listening to my music teacher and virtuoso organist play the most thrilling and memorable piece as the headmaster made his entrance.

Picture the scene.

Not only did I stop and listen to the whole piece on the radio, I came straight downstairs and played it over again on Spotify.  Magic!
