For many viewers, a particular highlight from last season was the inspiring interview with the late Donal Walsh from Kerry. (Donal was posthumously awarded the Young Person of the Year award at the People of the Year Awards.) Donny Osmond, comedian Sean Locke, writer Kinky Friedman, Coronation Street’s Helen Flanagan and Michael Bublé were also guests on the last series. But, hey, it’s another year and events that have not even happened yet will inspire the choice of some interesting guests, as the months progress. And some guests too who haven’t even “happened” yet - in terms of instant pop stardom yet to be granted- will only be delighted to arrive breathless and windswept to chat to Brendan.
