Last month, we flagged up Rinse FM’s series of video interviews to mark the station’s 18th birthday.

Some of the videos have been insightful, others have simply been entertaining (not that there’s anything wrong with that, of course), but the best to date has to be the 13 minute chat with Sarah Lockheart. Often known as Sarah Soulja, Lockhart has been a figure behind the scenes at Rinse FM for years, and was a driving force for the legendary former pirate finally receiving its FM license.

Now, if you want to know how to make an illegal station legal – and let’s face it, some of the information is out there but it’s hardly easy to find – this is essential viewing. If you head to Rinse’s YouTube channel, you can also watch newly-added chats with Scratcha DVA (including a recording of the moment where he found out that Rinse had got its license), Marcus Nasty, Roska and more.
