Actually, I’m amazed at how many young people I know are Beatles fans. My 22 year-old hipster daughter and a 26 year-old coworker, just to name two, love the Beatles.
My 26 year old son has loved the Beatles for quite some time now. I wonder if he’s your coworker! LOL! He bought the complete volume of their CDs that were released a couple of years ago and downloaded the entire thing to his laptop.
