Miriam and Alan: Lost in Scotland
9.15pm, Channel 4
“Gird your loins, Miriam … ” We’re off on a three-part campervan adventure around Scotland with TV’s new golden odd couple, Miriam Margolyes and Alan Cumming. Retracing their childhoods, the pair reveal their guarded vulnerable sides – one scene where Cumming recalls his troubled relationship with his father leaves his companion in tears. But these two can’t go too long without tickling an audience: Margolyes soon shares an anecdote about her knickers “falling off” moments before her driving test. It’s a cheeky carry on, warmed up with tender storytelling and wholesome tasks such as making tartan (but they do manage to crack a joke about vibrators in the factory). Hollie Richardson
