Would you believe what I heard?
I heard the Beatles.
Not the real Beatles. Not a recording. I heard clearly-recognizable renditions of Beatles songs, these being songs first released around fifty years earlier. Playing them, and rather well, was a lone Korean guy in his 30s or 40s. A small crowd was gathered around. He was asking for donations in the open guitar case but seemed to be playing more for the fun of it.
Earlier that year (2014), when I was in the USA, I recall some fanfare around the fiftieth anniversary of the Beatles appearing on the Ed Sullivan Show (whatever that was) for the first time in February 1964. By my count, that is over fifty years ago. Beatles music is still very popular and recognizable even after fifty years, and across the world. I also recall the Beatles were very popular in Kazakhstan, with life size bronze statues of the four Beatles on a hill overlooking the city, erected sometime in the 2000s.
