Billy Grammer was known for his two Top 20 hits 'I Wanna Go Home' and 'Gotta Travel On,' but also for inventing the Grammer Guitar. In the 1960s, it was called the "finest flat-top guitar on the market," and one that was made especially for Johnny Cash fetched over $130,000 at auction. The Illinois native was a member of the Grand Ole Opry and the Illinois Country Music Hall of Fame. He died in a hospital in Illinois in August 2011 at the age of 85.
