From Italian television, sometime in the late '50s or early '60s, please enjoy -- if possible -- the literally incredible Adriano Celantano...
...and his, shall we say, overly enthusiastic take on "Jailhouse Rock."
This guy has been a superstar in his native land and elsewhere for decades now, but I must confess I had never heard of him until last week, when a Ukranian émigré friend let it drop that Celentano's records were practically the only pop music you could hear in the old Soviet Union when he was a kid in the '80s. Poor guy.
In any case, you can hear Celentano cover some other early rock classics elsewhere on YouTube, including a performance of "Blueberry Hill" that makes Fats Domino sound like Metallica. You can also, occasionally, hear his music on the sound system at the fabulous Keuka Kafe Wine Bar on Queens Boulevard in Forest Hills, NY.
