In the final part of The Great British Faith, Hardeep Singh Kohli goes back to his hometown of Glasgow to explore how much it has changed, culturally and ethnically since he left 20 years ago.
We start this final leg by meeting his brother at the Sikh temple they both went to as boys, to reminisce about their Sundays worshipping there, before being taken to a Bollywood film in the city centre.
After meeting Rev Ian Galloway at Glasgow Cathedral, Hardeep drops in at a community centre in the Gorbals which brings together refugee and asylum-seekers from area-groups who would normally pass each other on the street.
He then meets Eddi Reader, formerly lead singer of Fairground Attraction, who shares her own spirituality and her love of Glasgow, which after 20 years in London she now calls home again.
The final leg of Hardeep's journey is an extremely personal and emotional one, as he goes back to his old Catholic school, St Aloysius. Here, with some of his old teachers, he explores how the school's philosophy of social justice has been a major factor in what he believes today.
