Just in case there's anyone out there who hasn't seen it, check out German rockabilly cover band The Baseballs with "Umbrella".
I'm not sure what I think of a "rockabilly" group that only does covers of modern songs, but hey, the boys can sing.
Maybe I should send them a can of Saint 21 pomade and see if they can be converted to real greasers.
Check out their debut album "Strike!" on Spotify.
