After previewing an extended clip for the upcoming sequel Mamma Mia! Here We Go Again, which features an elaborate performance sequence to ABBA’s “Super Trouper” led by Cher, Universal wrapped its CinemaCon presentation today with a surprise performance from Cher herself. The crooner treated the audience to a rendition of ABBA’s “Fernando.”

Cher was introduced by the film’s star Amanda Seyfried. Directed by Ol Parker, the film is set on the Greek island of Kalokairi and goes back and forth in time to show how relationships forged in the past resonate in the present. Meryl Streep, Julia Walters, Christine Baranski, Dominic Cooper, Pierce Brosnan, Stellan Skarsgård, Colin Firth, Andy Garcia, Lily James, Alexa Davies, Jessica Keenan Wynn, Jeremy Irvine, Josh Dylan and Hugh Skinner are also part of the ensemble.

Mamma Mia! Here We Go Again opens July 2o.
