Pick of the Day

Showbands - How Ireland Learned to Party, 9.35pm, RTÉ One

The 1960s in Ireland were extremely insular, very poor and priest-ridden. The Beatles and Swinging London seemed light years away - but young Irish people found a release in the showbands, a uniquely Irish phenomenon that was ultimately seen off by disco and rock.

It had its roots in the dancehalls of the 1950s, but the likes of Dickie Rock and Brendan Bowyer became superstars once television arrived and the showbands became household figures.

Here, Ardal O'Hanlon retraces the steps of these heroic troubadours across the length and breadth of Ireland (with an unlikely stop in Las Vegas) talking to the stars, hustlers and punters of this 15-year-long Irish cultural and social phenomenon.

New or Returning Shows

Dark Mon£y, 9.00pm, BBC One

This looks promising, and it's certainly topical. Screenwriter Levi David Addai had been working on this story before the #MeToo movement started and the controversial Michael Jackson documentary Leaving Neverland was released. But its subject matter is chillingly similar.

A struggling family accepts a substantial pay-off from a renowned filmmaker to keep silent about the molestation of their child. They felt this would enable the family to heal and move on - but the reality proves to be quite different.

The Honest Supermarket: What's Really in Our Food? 9.30pm, BBC Two

On average in the UK people visit the supermarket 221 times a year, but can the supermarkets be trusted to tell customers the truth about what's being bought?

Horizon creates a ground breaking supermarket with an onsite lab to uncover the truth. For example, lab tests reveal that many chickens are now grown so fast they contain more fat than protein.

This series is presented by Dr Hannah Fry (below) and Priya Tew.

Extreme Tribe: the Last Pygmies, 9.00pm, Channel 4

This new series revealing the lives of one of the most extraordinary societies on earth, as presenter Livia Simoka travels to the remote jungles of Congo, to live with a pygmy tribe, the Mbendjele.

They are almost entirely cut off from the outside world and, over five months, living on the floor of her adopted family's mud hut, Livia shares their personal family dramas and sees their tribal traditions, like female tooth sharpening.

In this first episode, Livia finds herself in the middle of two disputing families and finds out about the danger posed by a neighbouring hostile tribe.

Ghosts of the Deep: Ancient Shipwrecks, 9.00pm, More4

Here's a two-part documentary following a team of international scientists on a quest in the Black Sea to settle the enduring scientific puzzle of how it changed from a freshwater lake to a sea at the end of the last Ice Age.

Was it a catastrophic flood that could have inspired the biblical story of Noah's Ark or a slow inundation that happened over generations? The team survey and core the seabed in search of answers, but they also detect over 40 unusual sonar signatures.

Brexit: Behind Closed Doors, 10.45pm, RTÉ One

This two-part Storyville special was recently shown on the BBC and tells the untold story of the Brexit negotiations.

The difference is that it doesn't view the process from a UK perspective, but from the other side, with exclusive access to the EU Parliament's representative Guy Verhofstadt. It's quite illuminating.

Also tonight: at 8.30pm on BBC One there's a Panorama special where Jane Corbin examines the potential impact a no deal Brexit would have on the UK.
