Let us build a list of songs, any era, that people from every corner would hum together. I propose the rule: no lyrics about wars, borders or grudges, only songs about love, sea, trains, rain, weddings, work, longing for coffee.
Please name artist and song in plain text. Remember, this is a friendly list, not a ranking war. I will start with an old instrumental guitar piece that my father played and which still makes me stop whatever I am doing.
Also: who plays an instrument? Let us put together a session audio file and share it with credits.
