Episode 4 takes us back to the 1980s, the era of charity singles, random one-offs and iconic festive records.

The decade continued where the ’70s left off, with novelty and one-off successes for grandmas, Italian lovers and a random ’50s re-release.

There are also Christmas classics for years to come for Wham, The Pogues, Shakin’ Stevens, Cliff Richard and the charity behemoth of Band Aid.
