Guinness Ireland's documentary about Niall Horan and Lewis Capaldi's recent road trip around Ireland will air this Sunday on Virgin Media One.

The film, entitled Niall Horan’s Homecoming: The Road to Mullingar with Lewis Capaldi, was reportedly inspired by Horan’s desire to "revisit and reconnect with all that he loves of home; to retrace the origins of the exciting life journey he’s on and to experience the reality of Ireland today". 

And the former One Director star took his best pal, Scottish singer-songwriter Lewis Capaldi, along for the ride.

The film, captured over three days, will see the boys meet world-class guitar maker George Lowden, Tullamore artist Tolü Makay and Dublin busker, Jacob Koopman. Of course, a visit to the home of the black stuff, the Guinness Storehouse, is also on the itinerary.

Presumably, the film will also capture the moment the two hitmakers surprised fans on Grafton Street in Dublin with a busking session.

And hopefully, we'll also get to see some footage from the pair at Fleadh Cheoil na hEireann where they performed ‘Chasing Cars’ by Snow Patrol in a local pub.

You can watch Niall Horan’s Homecoming: The Road to Mullingar with Lewis Capaldi, on Virgin Media One this Sunday, October 16 at 10pm.
