I must confess that I wasn't interested in Rock and Roll in my youth, but I watched some movies about it. I was a teenage boy scout and more interested in folk songs, but I wanted to know what young people saw in it. In one film young Elvis explained what to do with your hips when dancing to this music, and heigh ho! I immediately understood why the girls raved about him. He looked not bad, indeed, with his interesting haircut.
I liked Bill Haley more, Little Richard I always thought funny.
Elvis the Pelvis' handshake was weak and not what I expected from an American private (he served in my hometown), but I must confess: He had a remarkable voice and could sing in different styles, e.g. Muß i' denn zum Städtele hinaus, an old German parting folk song.
Nowadays we have an Elvis-Presley-Place in the center of my town, and every year the fans (many mothers in their late 50s) congregate to remember his birthday and dying day.
