We take a trip down memory lane to rediscover what Christmas was like in the 1970s. With famous faces of the era - including Angela Rippon and Slade's Dave Hill - plus experts and historians, we take a nostalgic trip back to look at what was under the tree and in our stockings, what we were serving up for Christmas dinner, what was on TV, and the chart-topping Christmas tunes. Plus, we challenge a family to put away their smart phones and immerse themselves in Christmas of the 1970s!
