I thought Dean Martin sang this one. Maybe just on his own show.
The faint memory I have of either singer; I used to get Bobby Rydell mixed up with Bobby Darin. Both tended to perform wearing a suit jacket.
Most did. Class back then.
But there were many “Bobbys”. Seemed at the exact same time.
The Italian version ended up the #1 song of the year on Billboard.
The Rydell version was #54 on the year.
Oh, and yes, Dean Martin did sing it.
In the ‘50s, lots of acts covered the same song in a very short time.
