Adele at the BBC (BBC1, 8.30pm)

I'LL be amazed and disappointed if Someone Like You doesn't feature tonight in this rare glimpse of Londoner Adele Adkins, 27, who is probably the most reclusive owner of a £50 million fortune in pop history.

In this one-off, hour-long special, Adele will perform classic tracks as well as songs from her new album 25 – which by sheer coincidence is out today – accompanied by her live band, plus stopping to chat with GrahamNorton about her career and life to date.

It will be Adele’s first television performance since she performed Skyfall at the 85th Academy Awards in February 2013, where she won Best Original Song for the theme tune to the 23rd James Bond film.

Adele says: "I can't wait for the show. The BBC has been wonderful to me over the years and Graham and I get on great so it's going to be a laugh."

Graham Norton says: “This is the music event of the year and I'm thrilled to be part of bringing it to BBC1. This opportunity to spend an hour with Adele, her music and her stories is a truly rare treat. If I wasn't hosting this special I'd be sat at home watching it.”

The BBC has supported Adele since the beginning of her career. Her first song played on air was Daydreamer on Reggie Yates' BBC Radio 1 show. Hometown Glory featured on Zane Lowe's show on Radio 1 in 2007 and she made her debut television performance on Later with Jools Holland on BBC2 in the same year, performing Daydreamer.

Hopefully, the talk with Norton will reveal a little more than Adele is married, has a child and is unlikely to headline Glastonbury because she is uncomfortable in front of huge crowds. Her most revealing insight was announcing 25 on Facebook. In her post, she detailed some of her biggest regrets in life while also saying the latest release would be more of a "make-up" album because she aims to get to grips with the woman she has become "without realising".

The lead single from 25, Hello, broke records as it became the first song to reach a million digital sales in a week. It also hit the top of the charts in 23 countries, including the UK, where it became her second number one, following up from Someone Like You.

Adele has a huge range of hits to choose from tonight, and, hopefully she'll include Rolling in the Deep are included in the setlist, along with Chasing Pavements from debut album 19.

NCIS: New Orleans (C5, 9pm)

IN the first of tonight's pan-American Naval crime drama triple-bill (NCIS follows, while the LA spin-off gains a repeat showing at 10.55pm), LaSalle's brother Cade asks him for a big favour. Cade has no memory of the previous night's events, but the one thing he's sure of is that he's in trouble. His girlfriend, Wendy, has been killed and her body is in the boot of his car. Things begin to look even worse for the special agent's brother when his prints are found all over the murder weapon – a rope used to hang her. Understandably, the whole situation is taking quite a toll on LaSalle. Although his colleagues want to step in to help, no one is quite sure of whether Cade can be proved innocent – or even if he is.

Mercury Prize Live 2015 (BBC4, 9.30pm)

THERE are countless accolades within the music industry, but the Mercury Prize is arguably the UK and Ireland's most prestigious. Every year, a dozen albums from all genres are shortlisted, each receiving a specially commissioned Album of the Year trophy, as well as one being selected as overall winner by an independent panel of judges. Previous winners – including Primal Scream, Suede, Arctic Monkeys and Elbow – saw their profiles rise and sales soar. Who from this year's shortlist of Aphex Twin, Benjamin Clementine, C Duncan, ESKA, Florence and the Machine, Gaz Coombes, Ghostpoet, Jamie XX, Roisin Murphy, Slaves, SOAK and Wolf Alice will join their celebrated ranks?
