Wow!

Anka Warsaw concert cancelled by JFK assassination

"Paul Anka is back in Warsaw to perform a concert he had to cancel 48 years ago following the assassination of U.S. President John F. Kennedy."

Given that this was the height of the Cold War, I'm surprised he was even touring Poland. Looks like he was the among the first:

"Anka was among the first North American singers to have been allowed to tour behind the Iron Curtain at a time when Communist Poland was slowly opening up to Western popular culture."

I'm also surprised he's still going. Like Elvis, he picked the wrong time to become famous and his career just started to soar when the Beatles and Beatlemania knocked everyone else, including Anka, off the charts and the stages.
