The last 25 years has seen a noticeable increase in the number of permanent public sculptures in our towns, housing estates and roadways. How do these pieces get commissioned? Who is this art for? Who are the artists? In this documentary, the man who gurgles agreement noises for a living, Joe Duffy explores the colourful and controversial area of public art. Around Dublin and beyond, Joe meets the curators who decide on the sculptures in our streets and parks, the artists who make them, and the public who love and hate them. 9.55pm sees the new series of Blue Bloods, starring Tom Selleck, Donnie Wahlberg, Bridget Moynahan, Will Estes and Len Cariou.
