Roy Orbison came from the Great Beyond to woo the crowd with Pretty Woman.
Frankie Valli was seen in Largo, too, shaking it up during a rousing version of Sherry.
The Phantom of the Opera also took to the stage, twirling his signature mask and cape while laughing at the crowd.
The trio, who in real life are Jim Cameron, Warren Peace and Richard Breedlove, were part of the Adult and Senior Fall Talent Show held Thursday at the Largo Community Center.
The program featured 18 performers between the ages of 21 and 92, selected from about 30 contestants during two auditions last month.
The show ran 15 minutes longer than its two-hour schedule. But the sellout crowd of 250 clapped along until the finale, when the Handsome Daredevils, a barbershop quartet, kicked off God Bless America, a cappella.
"It didn't matter that it was long. I could've heard even more,'' said Elizabeth Goldstein of Largo. "I think it was just what the doctor ordered. One of the best I've seen.''
Judges for last month's auditions included volunteers from the Largo Community Center. After they made their notes, the center staff and event organizers made the final decision.
"I have no musical talent, but I have an ear for music,'' said Craig Dolan, recreation program supervisor. "And I can say that we have some good talent here.''
Eileen Crowell, a senior program specialist, believes the program, started about six years ago, has grown in popularity because of karaoke.
"We have a karaoke group here, and several singers in that group also sing karaoke other places in the county," she said. "I think this year has many new faces because word has spread.''
