It is 40 years since Sir Terry Wogan decided to leave Ireland and to seek his fortune across the water in England. In that time, Ireland has changed beyond all recognition - and so has Terry. Now, in the wake of his retirement from BBC Radio 2, Terry's going 'home'. In the autobiographical journey of a lifetime he travels back to Dublin, the city he left behind as a teenager, and all the way back to Limerick, where he was born, taking in the length and breadth of the heart-stoppingly beautiful Irish Coast en route.

Terry Wogan reaches the halfway mark in the odyssey around his homeland. He's travelled the southern half of the Republic, from Dublin round to Limerick, where Terry grew up. Now it's the turn of the north, much of which is quite literally a different country. After sharing memories of his buttoned-up childhood holidays in Galway and witnessing a seismic shift in Catholic prudery when 180 Irish ladies throw off all their clothes and take a 'Dip in the Nip' for charity, Terry heads for the border.
