Retro Hour, a UK-based retro gaming podcast, has posted an in-depth audio interview with Wing Commander composer George The Fat Man Sanger. They talk about the origins of his artist name, his early work for slot machines and Atari, the 7th Guest, creative process and the demo scene. The segment with Sanger starts at around the 21:30 mark and the subject briefly turns to Wing Commander at 39:00.
The Fatman was also one of the subjects of the game sound documentary Beep that came out earlier this year. A 45 minute video interview with Sanger was released as a free preview.
