To mark the eclipse – the first over the United States since August 2017 – Fallon and his team of crack writers engaged rock legends Heart to perform Bonnie Tyler's classic hit Total Eclipse Of The Heart during the actual eclipse, turning Jim Steinman's original song of vampire love into something that referenced both the event (the total eclipse) and the performers themselves, Heart. And, if that wasn't literal enough, Fallon sang the "turn around" part of the lyric while actually turning around.

"We have a special show tonight," said Fallon, by way of introduction. "Heart is our musical guest, and today is obviously the solar eclipse. So we thought, we have to do what we have to do. We have to sing Total Eclipse of the Heart with Heart, while watching the solar eclipse. Let's do this."

After this groundbreaking performance – which took place on the roof of the Rockerfeller Plaza in New York – Heart left the roof of the building and performed their classic 1977 hit Barracuda in the studio. Both clips can be watched below.
