Rumour has we've been discused on radio

One of our customers has just reported to me that they heard about the Dicky Bag on the radio.  Now bearing in mind we don't have the budget for radio advertising (yet) we are very keen to find out who was talking about it and what was being said.  Can any one out there help me further.  Did you hear it or were you the one talking about it.  Please don't keep me in suspense!!
