This is what we found on Wikipedia regarding the The FRIENDS™ Experience: The One in Dublin:

The 1989 World Tour was the fourth concert tour by the American singer-songwriter Taylor Swift, who embarked on it to support of her fifth studio album, 1989 (2014). Swift announced the tour's first dates in North America, Europe, Japan, and Oceania in November and December 2014. She announced additional dates for Singapore and China in June 2015, and a final announcement of the third show in Melbourne was made the following month.

The tour took seven months to plan and three months to rehearse. As with her previous tours, Swift was highly involved in the 1989 World Tour's planning and stage design. She aimed to create an intimate experience for concertgoers, which she found challenging for shows held in stadiums. Most songs on the set list were from 1989; additional songs from Swift's older albums were re-interpreted with a more synth-oriented production to align with 1989's soundscape. Each night of the tour, she performed one "surprise song" from her back catalog. The tour began on May 5, 2015, in Tokyo, Japan, and concluded on December 12, 2015, in Melbourne, Australia, spanning 85 shows. For many of the shows, Swift invited special guests onstage with her, including musicians, actors, athletes, and models, whom the media called her "squad".

The world's highest-grossing tour of 2015, the 1989 World Tour sold over 2.278 million tickets and grossed over $250.7 million. It was acclaimed by critics, who praised Swift's stage presence and connection with the audience. Meanwhile, her appearances with an array of special guests attracted commentary regarding her new image as a pop star—having previously been known as a country singer-songwriter—and the sense of authenticity that she had maintained. On December 20, 2015, Swift released the concert film The 1989 World Tour Live in partnership with Apple Music. Filmed at the November 28, 2015 show at ANZ Stadium in Sydney, Australia, the film features additional behind-the-scenes footage of special guests from other shows throughout North America and Europe.
