As the last person to win Mastermind before the series was cancelled, Mr McDouall said he relied on his "reptile brain" to dredge up the answers to questions asked by host Peter Sinclair.
It enabled him to answer the question "Who played the cello on the track Art Decade on the Low album?" with the correct answer: Edward Myer.
"Sometimes I didn't get it right, like when I had to name the illustrator who designed the album cover - his name was Neon Park, but when I had to answer the question on the show I said Pork."
So what is Hamish McDouall's favourite David Bowie song?
"Ashes to Ashes," he says without hesitation. But if you ask me tomorrow, it will probably be a different one."
Mr McDouall says he will catch up with a couple of Bowie fans and have a drink, and he also has a plan to mark 100 days of commemoration by posting links to his favourite 100 Bowie songs on Facebook.
After a 20-year break, a new series of Mastermind is in production and is likely to screen on TV One later this year.
