The far-reaching changes brought about by the new set of rules for Formula One have caused much discussion. In our April show Paul Jurd takes a look back to the changes in Formula One regulations over the years from pre-WW2 up to the more recent past. Josh Parsons from the Goodwood Road Racing Club talks about the upcoming Members Meeting and Matt Twynham from Twynhams Tours gives us a view into just how he organises his high-prestige events, and Jim Roller brings us the auction news. The team takes a look at Monaco Historique which also happens in April and dissect the entry grid-by-grid. Paul Tarsey gets the lowdown on a couple of American themed books from Jim and there is lot of chat about the historic racing scene.
