(CNN/MEREDITH) -- America's excitement for the eclipse on Monday had one unexpected effect: Bonnie Tyler's "Total Eclipse of the Heart" rose to the top of the charts becoming iTunes's number 1 song. Released on New Year's Eve in 1982, the 34-year-old song saw a resurgence as it became the unofficial theme song for eclipse viewers across the country.
In an interview with CNN Tyler even belted out her favorite line from "Total Eclipse of the Heart' live on Monday, just hours before a total solar eclipse is expected to darken parts of North America.
"I need you more than ever, and if you only hold me tight, we'll be holding on forever," she sang live from a cruise ship as CNN's John Berman held a lit flame from his New York anchor desk.
As passengers are plunged into darkness by the moon eclipsing the sun, they'll hear Tyler singing the rock ballad along with American band DNCE.
The Welsh singer said her song had to be edited down from its original eight minutes to a two-minute-and-40-seconds version because that's how long the total eclipse will last.
But Tyler is also likely to be singing the song, a No. 1 hit in several countries, in its entirety throughout the special day.
Asked by Berman if you can stare into a total eclipse of the heart without glasses, Tyler said: "That's a good one. I will definitely be wearing my glasses later, but I'm sure that you can look into my heart. I wear it on my sleeve."
