Puerto Rico: Olivia Newton-John Performs For Atlantis Cruise

Olivia Newton-John performs for Atlantis Cruises in San Juan, Puerto Rico

I'm out on the ocean aboard the gorgeous cruise ship, "Harmony of the Seas," with Atlantis Cruises as Olivia Newton-John was the surprise performer for the gay cruise audience in San Juan, Puerto Rico.

I wanted to share a couple of videos to show not only how terrific Olivia was but also the incredible response from the passengers.

I'm told the performance broke the record for the largest concert held on the open seas. Over 5,000 enthusiastic revelers cheered, sang along and gave love to Livvy from start to finish.

Olivia's band wasn't available on such short notice, so she was here solo. But, there just happened to be a full-scale production of Grease performing on the ship, so the production's "Danny," T-Birds and Pink ladies jumped in to help on "Summer Nights" and "You're the One That I Want."

It was a terrific night, and when Olivia sang "I Honestly Love You" she made it clear the sentiment was coming from her heart.

After the show, she posted on her social media, "This week I sang on the Atlantis gay cruise aboard the stunning “Harmony of the Seas" - the biggest ship in the world! It was amongst the most memorable of nights in my whole career! Fun, warm, loving people who shared those feelings with me! Thank you, Atlantis Cruises, Team Rich and Team ONJ!!!"

Watch some video footage below.

DJ duo Galantis performed after Olivia, and she made a point of chatching their show.

Largest concert on the open sea in history. Thank you @therealonj for you words, music and inspiration. 🙏🏻🙏🏻🙏🏻
