I turned 2 in 1975 and the first technology I became fascinated with was the record player and the big discs that came in colorful sleeves. I investigate the magic of records/LPs and how that year I had some of the best music of a generation in my ear as I traveled to England, Denmark, France, Italy and Greece - in a split-windscreen Combi-Van, of course. I also look at how I randomly encountered a man building his own airship using scrap junk and 30,000 litres of hydrogen. Welcome to the 1970s.
