Country legend Willie Nelson was left so inspired by Oscar movie favourite Brokeback Mountain, he's recorded a new song about gay cowboys.

The grizzled singer contributed a version of Bob Dylan's HE WAS A FRIEND OF MINE for the film soundtrack and now he has recorded a new version of Ned Sublette's 1981 quirky tune COWBOYS ARE FREQUENTLY, SECRETLY (FOND OF EACH OTHER).

Nelson recorded the song exclusively for iTunes, although plans are underway to include it on a future album and to produce a music video.

Nelson quips, "The song's been in the closet for 20 years. The timing's right for it to come out. I'm just opening the door."
