C.W. McCall had a surprise No. 1 hit in 1976. But he was actually an ad executive playing the character of a country singer. Sound Opinions producer Evan Chung tells the strange story of how “Convoy” became a cultural phenomenon. He speaks with the songwriters behind “Convoy” – ad executive-turned-lyricist/vocalist Bill Fries and composer Chip Davis (later of Mannheim Steamroller fame) – who reveal the origins of C.W. McCall in a series of Nebraska bread commercials. Like the song “Convoy” itself, it’s an odd, rollicking tale that takes many surprising turns.
