On the UK's BBC Radio 4 this evening, Front Row includes an interesting chat with Roger Waters. The 8-minute interview, which you can also hear below, includes Roger talking about the impact on his life the loss of his father had, and how this impacted his work - in particular, on The Wall.

In the interview, he also talks about Donald Trump's suggestion of building a wall between the US and Mexico, and discusses his new album and potential arena tour, which centres around the question: "Why are we killing the children?"

BBC Radio 4 can be heard on FM and DAB radio, digital cable, satellite and Freeview, and via the BBC website where they have the excellent "Listen Live" and "Listen Again" facilities, allowing you to hear the broadcasts for up to seven days following transmission.
