Music for Happy Shopping

I just remembered an important fact I want to record. About 3 years ago I was at a Mall at New York trying buy something worth of my time there. The speakers started playing the recent McCartney song from Memory Almost Full "Ever present Past". I felt happy to hear it playing through the radio there, and instantly got into a good mood, but when I turned over I saw this lady probably on her sixties and I saw her singing the choir "I do, I do I did..."  And she was singing it so happily just as if she were singing a Beatle song, I asked myself. Can she tell the difference? Does she know it's a recent production?... and after that.... I concluded, It don't matter!!!  If it's McCartney it's simply the same as if you where hearing a Beatle song. His music style is ageless.  That Mall should thank him for my happy shopping that day!
