David Lowe was outed on TikTok as the composer of some of TV's most iconic music when his 'how I created the BBC News themes' post to mark the 25th anniversary went viral!  He's the man behind the opening music for programmes like The One Show, Panorama, Grand Designs and BBC Countryfile, as well as top TV ads. And he arranged a special version of Chariots of Fire by Vangelis for the 2012 Olympic medal ceremony when Andy Murray took gold in the tennis.  David shows Helen how he builds the tracks, loved by millions of viewers. He's composed our new music for The Convex Conversation with guitarist James Nisbet, who plays for artists like Kylie Minogue & Belinda Carlisle, and West End trumpet player Jim Lynch on flugelhorn live in the studio.
