A universal pop song and the universe are about to align.

Guests aboard the Royal Caribbean's Total Eclipse Cruise have an extra surprise in store for their once-in-a-lifetime viewing experience: Bonnie Tyler, the Welsh songstress of "Total Eclipse of the Heart" fame, will be on board to perform her 1983 hit just as the moon sails across the sun. (The cruise ship will be positioned in the path of totality for this critical moment. “Bonnie Tyler was a natural choice for this once-in-a-lifetime moment," said the president and CEO of Royal Caribbean International, Michael Bayley.)

Tyler's song launched her to stardom and remains a classic today, especially as a karaoke favorite. But this is the first time she'll be performing it during this highly anticipated astronomical event.

" It’s going to be so exciting," Tyler told TIME, speaking from a brief stopover in Wales. "It doesn't happen very often, does it?"
