What is the name of this song? I've been hearing it in different houses and buildings ever since I was a child?

It's a song played by a band. Sounds like the Beatles or another band from that era. I've heard it in multiple houses and buildings, and it's been years since I've heard it, but the tune still floats in my head sometimes.<br><br>Is it possible that it's a song that was used in a commercial or movie or something? Or is there some sort of radio system that exisits that plays music in homes or buildings?<br><br>I have a vague memory of hearing it on a radio once, and I got the feeling that it was a commercial because it ended with a small spoken section, but I still don't know what it is.
