It's an F1 Heritage Parade in Monte-Carlo!

The Monaco Historic Grand Prix which takes place every two years is in full swing this weekend in the Principality.

The event brought together a collection of classic F1 cars and racers for a demo session on Saturday.

John Watson, Karun Chandok, Josh Hill (the grandson of five-time Monaco GP winner Graham Hill), local resident Thierry Boutsen, Riccardo Patrese, Eddie Irvine, Mika Häkkinen, Mark Blundell and Emanuele Pirro all enjoyed a "blast from the past" around the glitzy harbor.

Phillip van Osten

Motor racing was a backdrop from the outset in Phillip van Osten's life. Born in Southern California, Phillip grew up with the sights and sounds of fast cars thanks to his father, Dick van Osten, an editor and writer for Auto Speed and Sport and Motor Trend. Phillip's passion for racing grew even more when his family moved to Europe and he became acquainted with the extraordinary world of Grand Prix racing. He was an early contributor to the monthly French F1i Magazine, often providing a historic or business perspective on Formula 1's affairs. In 2012, he co-authored along with fellow journalist Pierre Van Vliet the English-language adaptation of a limited edition book devoted to the great Belgian driver Jacky Ickx. He also authored "The American Legacy in Formula 1", a book which recounts the trials and tribulations of American drivers in Grand Prix racing. Phillip is also a commentator for Belgian broadcaster Be.TV for the US Indycar series.
