UNCLE STEVE’s LIFE AS A TEENAGER IN THE 70’s

A. There was a lot less technology in those days, People didn’t have mobile phones and they didn’t text. They didn’t have the internet either, so when he wanted to research something for school, he had to go to the library!

B. Steve was into bands like Led Zeppelin, Queen and Pink Floyd. He remembers that The Beatles were breaking up then. There weren’t any MP3 players or CDs in those days. People played vinyl records on big record players.

C. Steve and his friends used to ride bikes and spend time at each other’s homes. There were no computer games, so he used to read a lot of books!

D. Fashion was fun and very colourful. Trousers with wide bottoms were trendy and skirts were all different lengths. It was fashionable for both girls and guys to have long hair
