The Real Marigold on Tour

The group is staying in the capital of the Sichuan Province, Chengdu. A bustling city of over 14 million, all the group find the language barrier difficult and Miriam in particular struggles with the regional cuisine. A swim in a high-tech pool in one of the world's biggest buildings makes a bad situation worse, as Miriam discovers a modern China at odds with her memory of it from a trip 30 years ago.

After experiencing city life, the group opt for an overnight stay in a country retreat. A ride on a high speed Bullet Train takes them up into the mountains surrounding the city.

At a local sanctuary, home to the Giant Panda, a feeding session leads to an emotional moment for Miriam, while Rosemary can't quite understand what all the fuss is about. Back in Chengdu a final night at the Sichuan Opera gives the group an opportunity to reflect on their bewildering and dazzling time in China.

Miriam Margoyles, Wayne Sleep, Bobby George and Jan Leeming reunite to head to the hot and vibrant city of Havana, Cuba, where life expectancy is high, food is rationed, and the way to travel is in iconic 50s cars.

The group stay in the capital Havana, and - after being wowed by the pink Cadillacs that pick them up from the airport - spend their first night learning to dance with the locals.

Later in the week Wayne visits a dance troupe and realises his classical training doesn't count for much when it comes to learning Cuban dance. But much to his joy he's invited to participate in the annual Cuban Carnival.

Sheila Ferguson, Rustie Lee, Paul Nicholas and Dennis Taylor reunite to head on an adventure to the cold but beautiful country of Iceland, where they split their time between a small fishing village and the capital, Reykjavik.

In Hausavik the ladies visit a senior citizens centre - much to Sheila's trepidation. Meanwhile, Paul and Dennis join an all-male choir and end up singing to a huge audience in a canyon. The team then reunite to head out whale watching and are moved to tears by what they see.

After experiencing the peaceful, slow pace of life in Hausavik the foursome head six hours south to the capital, where the pensioners pastimes include aqua aerobics and gymnastics. Paul tries his hand at a handstand for the first time in many (many) years!

Sheila goes on a date with an Icelandic man and realises that, despite living thousands of miles apart, they have a lot in common.

The group travel to the northern city of Chiang Mai, the cultural heart of the country, famous for its historic temples and laid back way of life. Once they've settled into their homestay, they venture out into the steamy 35 degrees heat.
