"What a Fool Believes" by The Doobie Brothers - 1979

This week Nicky J USA makes his hat-trick appearance and sails away with the 1979 yacht-rock anthem "What a Fool Believes" by The Doobie Brothers. Co-written by Kenny Loggins and Michael McDonald in a monumental collaboration, this song would end up being recorded and released by both artists, with only the Doobie's version reaching notable success. What are the 3 rules for creating a yacht-rock song? Which uncredited mega-pop star allegedly sang on this track? Which member of the Doobie Brothers later became a missile defense consultant for the US government based on his affinity for aviation magazines? All these questions and more will be answered on this week's episode of Single File.
