When John Lennon left Liverpool for the last time in 1968, he paused poignantly at the edge of Liverpool proper, turned to the assembled, tearful crowd, and exclaimed, “all you need is an annual contest to find the diddy,” before swaggering away, high on life and more LSD than any one person could safely consume in one sitting. The mayor of Liverpool, Thomas Tebbins (b.1923, d.1974), had no idea what Lennon meant, and attacked a group of schoolgirls with a garden hoe.
