A major letdown leads to the memory of a lifetime for one little girl from Jersey City.

Ten-year-old Geralynne Sunaz and her family had tickets to see UK singer Jamie Miller perform in Brooklyn last week.

Miller, who got his start on "The Voice UK," was forced to cancel, leaving fans like Sunaz without much hope of seeing their favorite performer.

After a few phone calls, however, Sunaz got the chance of a lifetime: singing a duet with him live.
