Task: Question Generation
Input (English): Passage: As the opening credits roll, a band called Flux, apparently with no singer, starts to play at a nightclub. Among the audience is a girl named Courtney Lane. Interspersed with the scenes of the band playing, singer Nikko Alexander calmly walks into the club through the back, barely making his cue for "Don't Tell Me". At the end of the song, he kicks over one of the amps, destroying it for effect. After the performance, the other members of Flux, upset by his carelessness, kick him out of the band; Nikko's girlfriend Amy, who is also in the band, dumps him. After the band members leave, Courtney frantically attempts to recruit Nikko into a show choir named "Spectacular!," of which she is leader. Though Nikko is skeptical and condescendingly rejects her offer, Courtney begs him to come to a carnival to see the choir perform and then make his decision.
Output (English): What is the last name of the person who is the leader of "Spectacular!"?
