One of the TV highlights of 2017 was a joyful two-parter which saw a group of pre-schoolers hang out in St Monica Trust, a home for the elderly.

The kids’ vitality, joy and curiosity had a hugely positive impact on the OAPs.

This special revisits St Monica’s to reunite old and young and asks how taking part in the show has impacted their lives.

At what can be a tough time of year for the elderly, the gang get in the festive spirit as they prepare for a carol concert and a visit from the big man in a red suit.
