Released in 1958 and, according to Wikipedia, the only foreign song that ever received a Grammy. One of the most successful Eurovision Song contest contributions, even though it did not win. That says everything about that sort of competition. High time to tab it. I just love that song.
This is just a rough sketch of the tune. It is perfect for adding strums, arpeggios and all kinds of embellishments around the melody.
[ A ] the intro, played very freely
[ B ] main theme, relaxed swing time feel
[ B ] the bridge, almost entirely made up of triplets, interesting harmony changes.
