Narrator: In the two, distinct groupings within the teenage population, the Mods go for groups like "The Zephyrs" we've just heard. And the Rockers go for less sophisticated surroundings. They prefer motorcycles to motor scooters. Their chief instrument is noise - in their music and their machines. Group identity is established by bizarre motifs on machines and clothes. Admission to this group is via a "ton-up", that is, achieving 100 miles an hour on their motorcycles. Their boast about this, matches their over-emphasis on masculinity. The atmosphere they wish to create is reminiscent of the behaviour of a gangster in a cheap, waterfront, flophouse. In their innocence, they've not yet realised that such over-emphasis calls the basis into question. Their attitude is assertive but aimless; their philosophy, negative.
