A very special guest joined the cast of “The Lion King” on Broadway for a surprise performance this weekend. The Tony Award-winning musical celebrated their 20th anniversary on Sunday and, to mark the occasion, Elton John played the piano and sang “Circle of Life,” the show’s iconic opening number.

The legendary singer-songwriter, who co-wrote the music for the 1994 animated film and the stage adaptation, joined the company, creative team (including director Julie Taymor and lyricist Tim Rice) and former cast members onstage at the Minskoff Theatre to conclude the anniversary celebrations. According to Playbill, original Nala Heather Headley and “Hamilton” alum and former Nala Renée Elise Goldsberry were also in attendance.

The post-curtain call performance wasn’t the only way the anniversary was honored. The Broadway show also debuted a Snapchat lens with Simba and Nala masks. The musical is also hosting a lottery for a free performance on Nov. 15. The hit Broadway musical broke a box office record in 2o14, grossing more than $6.2 billion worldwide.

“The Lion King” musical currently stars Jelani Remy as Simba, L. Steven Taylor as Mufasa, Adrienne Walker as Nala, Tshidi Manye as Rafiki and Stephen Carlile as Scar. The cast also features Jordan Toure and Tre Jones as young Simba, Aliyah Mastin and Mehret Marsh as young Nala, Cameron Pow, Fred Berman, Ben Jeffrey, Bonita J. Hamilton, James Brown-Orleans and Enrique Segura.

A live-action remake of the animated classic, starring Donald Glover, James Earl Jones and Beyoncé, is slated to make its debut in 2019.
