The Grammy-nominated musician passed away on 16 March (15) at his home in southern California.

Robertson penned hits in multiple genres, including early country-pop crossover hits like I Really Don't Want to Know, which has been recorded more than 200 times by artists such as Les Paul and Mary Ford.

His song I Don't Hurt Anymore started as a country track for Hank Snow, but proved to be a hit R&B single for Dinah Washington. It was also recorded by Bob Dylan, Martina MCBride and Jerry Lee Lewis, among others.

Robertson penned 15 songs for Elvis Presley, and wrote hits for Johnny Cash, Charley Pride and Della Reese, among others, while he also enjoyed chart success behind the microphone with his 1956 pop song The Happy Whistler.

He was inducted into the Nashville Songwriters Hall of Fame in 1972.
