Children In Need 2014 (BBC1, 7.30pm)

THIS is the biggest caper of the charity calendar. After 35 years, there's cause to look back over its long and illustrious history, as it not only features some of the biggest names in showbiz right now, but also a whole host of reunions and reboots from years gone by, making this potentially one of the most nostalgia-inspiring CINs ever.

Among the blasts from the past are acts as diverse as S Club 7, who will be “bringing it all back” in the name of charity, and cat-and-mouse cartoon legends Tom and Jerry, who return after an absence of some ten years or more for a one-off special escapade - alongside some of the BBC's biggest stars.

Bruce Forsyth is reunited with Tess Daly to host a junior version of Strictly Come Dancing providing a heart-warming chance to see the veteran professional back in action.

Tess, though, is busy enough already - she's co-hosting the whole event along with show veteran Terry Wogan. The pair ensures the night of fundraising fun gets off to a fine start by introducing the cast of the West End hit Charlie and the Chocolate Factory, who perform a spectacular all-singing all-dancing number, before the musical mayhem is transposed to Albert Square for an EastEnders song-and-dance routine. And that's not the only surprise in store from the Square, either, as later on in the evening, in what promises to be one of the night's most memorable sketches, Ian Beale is haunted by the jangling of Pat Butcher's earrings and Cindy's sharp tongue as they and a couple of other dead relatives come back to haunt him.

Doctor Who fans are in for a rare treat, too, as everyone's favourite Time Lord is on-hand for an exclusive one-off clip. Also, One Direction drop in to do their bit for the cause, Cheryl Fernandez-Versini performs a musical number, and Gareth Malone leads his All Star Choir through Wake Me Up, the official Children In Need single. Considering Gareth previously described working with the choir as being like "banging my head against the wall", it'll be interesting to see whether he's managed to hone them into a finely tuned unit in time for tonight's big show. Judging by his past form, if anyone can do it, Gareth's the man who can.

Lewis (ITV, 9pm)

ALEC Newman has rarely settled for the cosiest of roles. He appeared as a drug-addicted freedom-fighter in a TV version of Dune; was the eponymous scientist in a 2004 version of Frankenstein; a headmaster with anger-management issues in Waterloo Road, and more recently has been playing lethal slater Graham Lawrie in this two-parter.

Lawrie's arrest for the murders of three police officers led to one of Lewis's first big successes as a DI. Lawrie received a life sentence and, after being diagnosed as a psychopath during the trial, was incarcerated in a secure hospital. However, 13 years later, Lawrie is about to win his freedom, putting the detective's reputation in jeopardy.

In the concluding part of the story, as Maddox's life hangs in the balance, Lewis joins Hathaway on the case, but they struggle to work well together. The cast includes North-East actor Kevin Whately, Laurence Fox and Clare Holman.

Bob Harris: My Nashville (BBC4, 10pm)

WHISPERING Bob Harris is the best candidate to give us the lowdown (or do I mean hoedown?) on Tennessee's most famous musical region. The seasoned broadcaster journeys to America's country music capital and reveals why Nashville became Music City USA.

From the early days of the Grand Ole Opry on commercial radio, through the threatening onset of rock 'n' roll in the 1950s, up to the contemporary mainstream hits of Music Row, this film examines how music has shaped Nashville, and why in 2014 it's a place of pilgrimage for musicians the world over.

There are performances from the region's top talent as well as interviews with Emmylou Harris, Duane Eddy, Dave Stewart and Rosanne Cash.
