Is local radio in England worth its £110 million budget? Roger returns to his home county of Cumbria to speak to listeners there about why their local BBC radio station is one of the most popular in the country.

And you wanted to hear more from Sharon Shoesmith, the former director of Haringey children's services. Maybe you would have if it was someone other than John Humphrys interviewing her on The Today programme.

How many children listen to the radio in the middle of the night? None we hope, so why are so many of you being kept awake by CBeebies programmes at 2 o'clock in the morning? Radio 4's Network Manager Denis Nowlan explains.

And what exactly is a lamb bank? Well it helps save the lives of thousands of lambs each year - and there no bonuses involved.

Contact the Feedback team to let Roger know what else you'd like him to tackle this series about anything you've heard on BBC radio.
