I haven't heard it and think she probably would've mentioned it on the forums if it were true so I'd say he's probably incorrect BUT I wouldn't rule it out completely in the future! You never know....
I must have subconsciously thought this was very unlikely, as I keep reading the thread title as "Cathe doing radio ABS" (not that I have any idea what "radio abs" are, but they must seem more likely than radio ads, LOL!)
