Russell WatsonWe’ve all been inspired by Gareth Malone to get singing, and this programme follows a choir with a greater reason than most to warm up their vocal chords.

The documentary follows The Big C choir, made up of 35 cancer patients who test the theory that singing in a group directly benefits your wellbeing.

Opera superstar and brain cancer survivor Russell Watson joins the choir to give them some tips. ‘I’ll never be 100 per cent free of cancer because all of my tumour couldn’t be taken out by surgery,’ Russell explains.

‘But I’m alive and well, and very positive. Initially, they told me I wouldn’t be able to sing again, but I’m singing better than ever.’

Sing For Your Life is on C4 tonight at 8pm.
