In this month's episode, Ian and Mick meet the Scottish film director Grant McPhee who's making a three-part documentary series on the untold story of Liverpool's arts and music underground scene from 1964 to 1984 - "Revolutionary Spirit".

Contrary to popular belief, the Merseyside music scene didn't collapse after the Beatles left the city in the 60's. There was a thriving underground scene before,during and after the Fab Four which paved the way for the 2nd Mersey Music explosion in the early 80's.

Grant discusses his first documentary in the series, 'The Pool of Life', which tells the story of the legendary Liverpool School of Language, Music, Dream and Pun - how it started and what it led to ; with some incredible archive footage from the 70's that has never been seen publicly before.Grant describes it as 'The Greatest Story Never Told'
