Past Forward: A Century of Sound, hosted by Greg Jenner, returns to BBC Radio 4 and BBC Sounds at 1:45pm for the next two weeks. Starting Monday 21st March, Past Forward uses a random date generator to alight somewhere in the BBC's vast archive over the past 100 years. Greg hears an archive clip for the first time at the top of the programme, and uses it as a starting point in a journey towards the present day.
