A scrap or two of memorable chorus, great thunking drums to cover up how negligible the verses are, mostly exhausted vocals, plenty of repeats to try and bang it all home. A weak song, and an ugly sounding, hollowed-out record – the big thin sound of “Chain Reaction” imploded like an squashed plastic bottle. Every time I play it I want to unpop my ears and check I’ve not got a 64kbps bitrate version by mistake. If “You Win Again” had be their only number one you could approach it with sadness and affection as a long-service medal. Instead I know how much better they can do: this is the dust at the bottom of the Bee Gees cereal packet.
