Country superstar Garth Brooks' retirement is over - he has recorded a new tribute tune to late pal CHRIS LEDOUX and plans to release it as a single.

After a year spent making surprise one-off appearances at charity shows, the singer/songwriter has recorded a new song exclusively for America's Wal-Mart supermarket chain.

GOOD RIDE COWBOY honours his rodeo pal LeDoux, who died earlier this year (05). It's Brooks' first official release for two years.

Singing cowboy LeDoux lost his battle with cancer at the age of 56 in March (05).

The former world champion bareback rider became a country music star when he started writing and recording tunes about his rodeo days, and struck it big in 1992 when he duetted with superfan Brooks on WHATCHA GONNA DO WITH A COWBOY?
