My better half was away for the weekend so I had to do a more than usually convincing imitation of a taxi driver: sleepovers, parties, sports, etc. However, there was one big consolation. All weekend a local radio station, Radio Nostalgie, played nothing but 1970s music. It was a wonderful aural trip down Memory Lane. The various hits and songs triggered all sorts of memories of my late teens and university years, but the feast also led me to realise just how extraordinarily rich and fertile that decade was in musical terms.
