“The Boat That Rocked” is an ensemble comedy in which the romance takes place between the young people of the ’60s and pop music. It’s about a band of rogue DJs that captivated Britain, playing the music that defined a generation and standing up to a government that, incomprehensibly, preferred jazz. The Count, a big, brash, American god of the airwaves; Quentin, the boss of Radio Rock — a pirate radio.
