Top Single: This Week in 1960

The No. 1 single 45 years ago today was "It's Now or Never" by Elvis Presley. I didn't know this until I looked it up, but "It's Now or Never" is Elvis's biggest-selling single, with total international sales topping 20 million. That paid for a lot of peanut butter and bacon sandwiches at Graceland.

This song had legs, as the saying goes. In America, it became No. 1 on August 15, 1960, and stayed at the top for five weeks in a row, finally getting knocked off by Chubby Checker's "The Twist." In Britain, "It's Now or Never" stayed at No. 1 for eight weeks.

The song had a more adult, operatic sound than anything Elvis had sung up to this point. It was based on "O Sole Mio," an Italian song written in 1901 and made popular by Mario Lanza. It was reported to be Elvis's personal favorite of all his songs, beating out even "Do the Clam."

3. I'm Sorry -- Brenda Lee
