TV tonight: the biggest names in country make a noise in Nashville

Grand Ole Opry: Opry Live

7pm, Sky Arts

“The show that made country music famous” (according to its own branding), the Grand Ole Opry celebrates its centennial season. Striding on to the stage in Nashville this weekend are Carrie Underwood (belting lungs and contemporary-style hits); Grammy‑winning Kathy Mattea (character‑driven, intimate storytelling); and Suzy Bogguss (folk and Americana influences).

Border Force: America’s Gatekeepers

7pm, U&Dave

A depressing look at the work of customs and border protection officers on the US/Mexico border. The week’s cases include a female pedestrian with an outstanding warrant for larceny returning from a day in Mexico, and two women caught in a car with illegal diet pills stashed in it. Hollie Richardson

Beethoven’s Fifth at the Proms

9pm, BBC Four

A specially curated Proms night, presenting archive performances of Beethoven’s “supercharged” Symphony No 5 in C minor, Mussorgsky’s Night on a Bare Mountain and Strauss’s audacious Don Juan. Petroc Trelawny and Georgia Mann host, the BBC Symphony Orchestra essays the bangers, and the baton-wagglers are Marin Alsop and Elim Chan. AC

Last year’s fire next to Glasgow Central station meant that the city’s amateur pianists travelled to London to play for Claudia, Mika and this week’s guest judge Jamie Cullum. Among them are Paul, whose right hand lost its function after a brain tumour operation at 17 – but he didn’t let it stop him. HR

Love Island

9pm, ITV2

What a messy week it’s been! Lola and Sean gritted their teeth as they “willingly” left the villa before they could be dumped, while Ellie has also walked after days of tears. With the final imminent, surely it’s time for the couples to put on a united front? Hannah J Davies

Unacceptable

9pm, TLC

The panel show that dares comedians to say the unsayable in front of a live audience continues. Captains Richard Ayoade and Joanne McNally are accomplished provocateurs – and joining them this week for full-frontal assaults on received wisdom are Alex Brooker, Kiell Smith-Bynoe, Lou Sanders and Sarah Keyworth.
