"Memories are made of this" ...
I still remember this song in it's German version "Brennend heißer Wüstensand" (Burning hot desert sand) sung by Freddy Quinn. It was the absolute hit over here in 1957.
When I worked with the regulation service during the National Lutheran Convention in Frankfurt, a hot dog vendor near my working place played it all the day, sometimes changing to the other side (16 tons? I'm not so sure today.)
A good musician can play any kind of music, except maybe 12-tone-music. So why not folk?
