Former pirate radio presenters Dave Cash and Roger Day take a look back at the pirates' heyday to celebrate the release of The Boat That Rocked.
Dave hears from the film director Richard Curtis and stars Nick Frost and Bill Nighy about the motivation behind the project and their own experiences of the swinging pirate stations in the Sixties.
Richard says: "I'm so honoured to be talking to you, this is really spooky. This is a great, great, great moment for me. This is like travelling back down the corridor of time and diving into my Roberts radio."
Bill Nighy shares his memories of the time that generated BBC Radio 1: "You could actually for the first time hear all of the new music all the time, and myself and 22 million other people tuned in everyday. It's hard to explain now, what a big deal it was… there this violent contrast, this change in the music. It went directly from your mum and dad's music which was rather staid, conservative… to Jimi Hendrix burning his guitar, The Who and the Rolling Stones."
There will be a chance to hear some real pirate radio with classic moments taken from Dave's show with his former shipmate, the late Kenny Everett, and the final hour of Radio London, the station they broadcast on, before it was shut down by the Marine Broadcasting Offences Act in 1967.
