Miriam O'Callaghan is back again for another installment of her summer chat show tomorrow night, with a bit of an 'RTE canteen' lineup but sure should make for an entertaining enough hour or so.

Joining Miriam tonight will be former Leinster and Ireland star Luke Fitzgerald, in what will be his first broadcast interview since retiring.  He'll be chatting about what led him to the difficult decision to leave the sport he loved and his plans for the future.

Irish model Roz Purcell will be talking to Miriam alongside her sister Rachel who has just recently been diagnosed with chronic myeloid leukaemia.

Also on the show, the always entertaining Mary O'Rourke will be in to chat to Miriam about the rise of woman in politics and her upcoming book 'Letters of my Life'.

Finally, there will be music from singer songwriter Calum Scott performing his hit single ‘Dancing on My Own’, a cover of Robyn's original hit from 2010.

Saturday Night with Miriam will be at the later time of 10.20pm, following Mrs Brown's Boys Live at 9.45pm.
