I don’t think I will ever stop being grateful for You Tube music videos. I think what I love most about You Tube music video is that they allow you to travel through space and time without actually having to move a muscle. You can use You Tube music videos to visit any decade in recent history. You can also listen to music of every genre from any country, and in doing so learn more about the culture and traditions of other places.
One of my favorite You Tube music videos is actually a tribute to the late Greek actress, singer and politician Melina Mercouri, and it features a song called Never on a Sunday, which comes from the movie of the same name.  Never on a Sunday is a song about a Greek prostitute. Despite her profession, the prostitute still has some moral integrity and respect for God and religion, which is why she never does business on a Sunday.
The above clip is one of my very favorite You Tube music videos because it takes me back in time to the period when I lived and worked in Athens, Greece. Never on a Sunday is a very famous song in Greece, and a singer who performed at one of my favorite restaurants often sang it.
