Tv host and NFL great Terry Bradshaw has been busy rehearsing for his Vegas show, “A Life in Four Quarters.” Producer Anita Mann tells us the musical will even include a halftime number. Backup singers called the IQuties and his daughter Rachel will join him. “Terry is dancing and moves beautifully,” Mann says. “He sang in church and has a gospel kind of sound, but he can also do ‘Phantom of the Opera’ . . . Well maybe not, but a fun voice.” The show runs June 28 and 29 at the Mirage.
