Each year on the anniversary of John Lennon’s death, his son Julian thanks his Facebook followers for their heartfelt condolences, and asks them to buck up, remember the good times, and not wallow in sadness. Right on, Jules. Even though I shed a tear each and every December 8th – the date of John’s murder in 1980 – this year I'd like to present an upbeat memorial to the man whose music changed my life. How about a little story about his influence on the city of Prague, the capital of the Czech Republic, where the Lennon Wall - Lennonova Zeď - stands as a symbol of freedom.
