As many a teenager will testify, historical facts and figures can be notoriously difficult to recall.

But one teacher has come up with a way to keep the past alive in the minds of his students – a system of revision based on Abba songs.

Rick Rogers has posted the reworked songs on Youtube – with apologies to Abba songwriters Bjorn and Benny – to help his GCSE students remember key facts about Nazi Germany.

The curriculum leader of history at Benton Park School in Rawdon, can be seen singing the pieces while accompanying himself on guitar.
