There are only two people in the world who “waft” to their destinations. One is Lorraine Chase, who famously did so from Luton Airport, rather than paradise, in the old Campari ads. The other is Joanna Lumley.

Having previously wafted her way along the Silk Road, and across Japan, India and Greece, Joanna Lumley’s Hidden Caribbean (STV, Tuesday) found the Ab Fab star in Havana at the start of a 1500-mile trip to Haiti.

Despite the “hidden” tag in the title, Lumley did all the things every other travel presenter does in Cuba, from taking a ride in a classic car to visiting a cigar factory. Though she did sneak a peek at some luxury cabins, built in the sea, that are part of the island’s dip into five-star tourism. A snip at $5000 a night for the best one, she did not think “Che and Fidel” would approve.

Lumley was on first name terms with everyone, including long dead revolutionaries. With that breathy voice and her touchy feely style, the 73-year-old (SEVENTY FLAMING THREE!) floats along on a cloud of luvvieness, blowing air kisses and making friends. On a trip through a mangrove forest she spied a marmot-like creature climbing through some branches. Within seconds it was eating a cracker out of her hand. Well, wouldn’t you?

The Great Celebrity Bake Off for Stand Up to Cancer (Channel 4, Tuesday, above) has gone up in the world since the days when Ruth Davidson took part. This time around, in place of common or garden leaders of the Scottish Conservatives, as Ms D then was, the bakers for charity include the Oscar-winning actor Richard Dreyfuss. He wasn’t in the first episode – you have to build up to these things – so we made do with documentary maker Louis Theroux, comedians Jenny Eclair and Russell Howard, and Ovie Soko, the basketball player.

Man, Theroux is competitive. At one point he was piping cream into a choux bun with such intensity the pastry exploded.

The technical challenge was custard slices, or Mille-feuille as they are known in the Milngavie branch of Greggs. Judge Paul Hollywood found the delicate pastries awkward to eat. There is no elegant way to do this, he said, stuffing a cake into his gob, just as fellow judge Prue Leith picked up a knife and fork and showed him how it was done.

There are a lot of edgy new comedies around. Perhaps it comes with the times. Then again, you would think when days are difficult viewers would want a retreat into silliness. While that audience is still catered for (see Dad’s Army every Saturday night) the way to catch a commissioner’s eye is to wander places sitcoms generally do not go.

Who would have thought, for instance, that there was a sitcom in Syria and the refugee crisis. The second series of Home (Channel 4, Wednesday) has been tough going at times, what with Peter (Rufus Jones, also the writer), losing his job, refugee Sami (Youssef Kerkour) losing the will to keep going, and Katy (Rebekah Staton), the woman who took Sami in, losing her rag with a pupil and being suspended. To top it all, Dougie Henshall turned up as Katy’s ex. No more DI Jimmy “Nice Guy” Perez from Shetland, alas; his character was a swine of the highest order.

Just when you thought it was going to be impossible to lift the characters out of their gloom, Jones led a fightback. Love, decency, and some pretty fine gags won the day. As for you, Mr Henshall, get back to Shetland and start being lovably tragic in a pea coat again.

Also from the edgy comedy drawer was Breeders (Sky 1, Thursday). Created by Martin Freeman, who also stars, it’s a sitcom that’s about as far from My Family as it is possible to get. Good, you might think, a clear-eyed view of modern parenting, swearing and all.

It was very watchable, but I must admit, when Freeman’s character effed and blinded at his squabbling kids it felt a little too on the edge. Maybe it was because they were only wee. Teenagers might have been different. Nor was I sure about some lines. “I would die for those kids,” said dad, “but often I also want to kill them.” You know what he means, but still.

I’ll tell you who did deserve a rollicking –the panel on Dragon’s Den (BBC2, Sunday). I had not watched in a while but I cannot remember the dragons being so rude. Tough, yes, but not so relentlessly grumpy.

Some of the cash-seeking contestants were clearly being led on as lambs to the slaughter, including the young American, inventor of beauty brushes, who thought the population of the UK was 200 million. The only thing that got the dragons smiling was a dog riding on the back of a pony as part of a pitch for a grooming tool. But when it came time to pony up they were not keen on that gizmo either.

Please, TV gods, let the dad from Breeders turn up tomorrow.
