Dublin-born radio presenter and producer Greg McQuaid is doing his bit for Breast Cancer Awareness in San Francisco - with the help of stars such as Spandau Ballet and Graham Nash of Crosby, Stills, Nash & Young.

McQuaid works on the city's KFOG in the Morning breakfast show and came up with the idea of an ongoing musical collaboration started by himself and co-presenters Renee Richardson and Mike 'No Name' Nelson.

Looking for a creative way to involve various musical guests in a year-long project, Irish Greg (yep, that's what they call him) hit upon an idea after `No Name' Nelson told a story about his eight-year-old son.

The boy had shoved a piece of CD-shaped paper into a CD player with the words 'Boob Spelled Backwards Is Boob' written on it, and that palindrome intrigued his father.

"No Name asked why he did it and was told by his son that he had a song stuck in his head called Boob Spelled Backwards Is Boob and wanted to hear what it sounded like," McQuaid explains.

"That sparked the idea that the show would then ask all musical guests that visited the station in 2015 to help get the song out of the kid's head and make a proper song.

"Given that No Name's wife was in recovery from breast cancer, it was decided that when the song was completed it would be sold to benefit a yet to be determined cancer charity, hopefully coinciding with Breast Cancer Awareness Month in October."

So far, contributors include Tony Hadley and Steve Norman of Spandau Ballet, Graham Nash of Crosby, Stills, Nash & Young fame, former Red and Green's Chuck Prophet and his wife Stephanie Finch, and Californian singer/songwriter Megan Slankard.
