TV Times top picks for tonight

What’s on telly tonight? Here the TV Times team of expert reviewers highlight the best shows on Wednesday 4th July

The Big NHS Singalong, 9pm, ITV

The NHS Choir first found fame on BBC2’s Sing While You Work in 2012 and then went on to beat Justin Bieber to the 2015 Christmas No 1 with A Bridge over You. Now they want to make headlines again as they attempt to break the world record for Most People Singing on a Radio Broadcast to celebrate the NHS’s 70th birthday. Ashley Banjo and Sara Cox present the performance as the choir is joined by other NHS workers from around the country and a host of singing stars. The song, A Little Help from My Friends (what else!), will be available to download in aid of NHS Charities Together. Rating: *****

Rich Hall’s Working for the American Dream, 9pm, BBC4

Comedian Rich Hall presents a personal ride through US history – from the first pilgrims landing in 1620 to the Trump-voting mobile phone addicts of today. What does the American dream mean and how does it shape the idea of the ‘land of opportunity’. Rich explains it’s a simple idea – ‘put in a little elbow grease and your efforts will be rewarded’. But how does that work for the factory worker toiling 70 hours a week who still doesn’t earn enough to feed the family? Rating: ****

The Highland Midwife, 8pm, Channel 5

We’re at the sharp end with midwives Hayley, Helen and Lydia tonight, as they deal with births from out in the wilds to the hi-tech sanctuary of a city hospital. How is Lydia going to get on with Gordon, who is determined to be a hands-on dad and wants to be totally involved in the delivery. Is he going to get in the way? Rating: ***
