Ripper Street star Charlene McKenna and Fair City's Clelia Murphy are among the guests joining Miriam this week.

Fair City’s Clelia Murphy (aka Niamh) talks toy boys on Ireland’s favourite soap and how she’s achieved her great new look.

Businessman Niall Harbison tells Miriam the reason he wrote his book, Get Sh*t Done, and how he managed to pull off a multimillion euro deal while battling his demons.

Miriam talks to the inspirational couple Simon and Ruth Fitzmaurice about Simon’s Motor Neuron Disease, and they discuss his new book It’s Not Yet Dark and his plans to make a movie.

All that, plus music from James Vincent McMorrow, on Saturday Night with Miriam at 9.20pm on RTÉ One.
