THERE'S no football today, so here's what you can watch instead.

The Big NHS Singalong (ITV, 9pm)

There have been lots of programmes to mark the 70th anniversary of the NHS, and many of them have made a point of celebrating the service's unsung heroes.

But now those unsung heroes get a chance to belt out a tune for all they are worth as part of The NHS Big Singalong.

That's because the NHS Choir is being joined by popstars and celebrities in a bid to smash the world record for the biggest singalong ever to be broadcast.

The song they will be performing is The Beatles' classic With a Little Help from My Friends (presumably more people knew the words to that than to the Fab Four's more medically minded Doctor Robert).

But breaking a record doesn't just take dedication, it also requires organisation, and in this programme presenters Sara Cox and Ashley Banjo follow the build-up to the big event.

It's a cause that's clearly close to both their hearts. Sara said: "It is so exciting to be part of this challenge to break a world record and celebrate the amazing work of the NHS. We'll be travelling the length and breadth of the UK recruiting people to join in to make sure we smash that record and show everyone working in our NHS how much we appreciate them."

Ashley added: "We want to recognise and celebrate the hardworking and dedicated staff who keep the NHS going every day and highlight the human kindness at the heart of the incredible care and treatment they make available to every single one of us."

The pair will be charting the progress of choirmasters doctor Katie Rogerson and NHS worker Joe Blunden as they scour the health service for potential warblers, while also recruiting a few famous performers.

In the process, we'll meet some extraordinary patients and staff, and find out why some of the celebrity recruits have very personal reasons for wanting to support the NHS.

Once the singers are assembled, the presenters will be joining the Lewisham and Greenwich NHS Choir and their famous friends at the iconic Abbey Road studios, where the Beatles recorded the original track.

And more choirs and staff will be joining in from hospitals and other locations across the UK, with one group performing on the cobbles of Coronation Street.

Hopefully, it will be a record-breaking effort, but Joe Blunden's ambitions don't quite stop there. Cameras will also capture the excitement when a version of the song is recorded at Abbey Road, ready to be released as a charity single.

Joe says: "We are determined to both smash that singalong record and get to number one!"

And seeing as the Lewisham and Greenwich NHS Choir previously held Justin Bieber at bay to claim the 2015 Christmas number one with A Bridge Over You, maybe, with a little help from the health service's many friends, his dream will come true.

Street Food Servants (BBC1, regions vary)

The fascinating Our Lives strand continues with this documentary, which was originally broadcast last months in the London area, but can now be seen by the rest of the country. Anita Rani tells the story of one man who has devoted his life to helping the homeless. Randeep Singh started his small charity in Southall, London, with just a handful of volunteers but has now transformed it into a sophisticated national task force feeding and clothing thousands of people every week. He is now looking to expand, but that brings a new set of challenges.

The Highland Midwife (C5, 8pm)

Community midwife Hayley undertakes a journey from the heart of the Highlands to the city hospital, to help with the delivery of mum Rachel's baby. Meanwhile, in Campbeltown on the west coast, first-time mother Morven is determined to have a local birth and midwife Helen must decide on the safest option for her and the baby, and in Aberdeen, midwife Lydia is assisted by hands-on dad Gordon, who is keen to help deliver his new baby. Narrated by Pam Ferris.

Rich Hall's Working for the American Dream (BBC4, 9pm)

In his previous BBC4 documentaries, comedian Rich Hall has tackled different aspects of US culture, from depictions of Native Americans and the South to the history of bitter presidential election campaigns. But his new film sees him exploring arguably the biggest subject of all - the American dream. Since the pilgrims arrived on Plymouth Rock, America has been sold as the land of opportunity, where if you work hard, you can succeed. Hall looks at how this ideal has been perpetuated by politicians and artists alike and asks what happens when the dream turns into a nightmare.
