In The Wrinkled Stocking Tea Room anorak-clad tourists sheltering from a downpour tuck into barm cakes or a Batty's Big Breakfast.

On the cafe walls are signed photos of actors Kathy Staff and Bill Owen Nora Batty and Compo, the star-crossed lovers of the worlds longest-running TV sitcom.

Outside, other visitors brave the rain to pose for photos on the steps of Scarfold, the stone cottage where, for three decades, unlikely sex symbol Nora used her broom to fend off the amorous advances of her welly-clad admirer. Next door folk from as far afield as Canada, Australia and New Zealand queue for tickets to the Last of the Summer Wine exhibition, where Nora's pink bloomers and Compos grubby long johns hang on display.

This is Holmfirth, the former mill town in the picturesque Holme Valley near Huddersfield, West Yorks, where the BBC's most iconic comedy series has been filmed since 1973.

It is a mecca for Summer Wine fans from around the globe and the local economy has flourished as 20,000 tourists a year boost the cafms, gift shops and coach tours of TV locations.

But tonight sad locals will be among millions of viewers watching the finale of this national institution after 37 years, 31 series, 295 episodes and millions of laughs.

Trendy TV executives have been itching to axe the show for years, believing the juvenile antics of delinquent pensioners were out of touch with modern society.

And viewing figures that peaked at 18.5million in 1985 have averaged just four million per BBC1 episode in recent years.

Yet fans in 25 countries still love Summer Wine for the very reason it hasn't changed as it focuses on the lives of men who refuse to grow old gracefully but prefer to ride bathtubs downhill or harass women while overdosing on tea and crumpets. But when the last drops of the vintage show drain away tonight, what does the future hold for Compo, Clegg and Foggy's old stomping ground?

Will tourists stop coming to Holmfirth to pay homage?

Bakery owner Greg Christofi, 47, parish councillor and president of the Holme Valley Business Association, said: Ive lived here for 25 years and Last of the Summer Wine has been a huge part of our lives. The cast have become good friends and the series has brought a lot of tourism 20 per cent of my income comes from tourists.

Its very sad to see it end and a lot of businesses are worried about whether the fans will keep coming.

The repeats will go on for a few years but its inevitable that numbers will dwindle so we have to find other ways of promoting the area. We are holding food and drink, film and folk festivals and a flower show. And we have s200,000 funding to build a heritage park celebrating all aspects of our history.

There will be a section on Summer Wine and we still plan a statue of Compo Bill Owen. But we will not be spending s50,000 as discussed more like s20,000. Holmfirth needs to move on. We wont forget but cant rely on a show no longer on TV. Local Tory MP Jason McCartney used his maiden speech to Parliament in June to raise his worries about the loss of Summer Wine trade in his constituency.

But not everyone shares the fears. On the day I visited Holmfirth a steady stream of tourists poured into Sids Cafm where Compo and Co would sit plotting their next caper over a cuppa.

Owner Laura Dittley, 40, said: Were as busy as ever and I don't think the end of the show will make much difference.

People still go the Heartbeat set even though that show has finished. Summer Wine was much longer running. We get loads of foreign tourists, especially Americans.

In the States they are a few years behind some of them don't even know Compo is dead. The scruffy, ferret-loving character was killed off in a moving storyline when veteran actor Bill Owen died in 1999.

Bill is buried in a churchyard just outside town overlooking the landscape he came to call home.

Laura, surrounded by Summer Wine tea towels, aprons, T-shirts, mugs and other souvenirs for sale, said: We usually have a statue of Compo out front and fans love posing for photos next to him, even though someone pinched his woolly hat.

Where is he today? Out the back, Laura replies. The winter wasn't kind to Compo. He got tatty and smelly and was putting people off. Nora knew the feeling.

Fans flock to see Nora's house at 28 Huddersfield Road. The most devoted can rent the two-bedroom terrace for s270 to s665 a month and get the Nora Batty Experience.

Owners Neil and Nicola Worthington have decked out the property with 1950s-style furnishings and props from the show, including Nora's broom and pinnies.

Neil said: When rain dripped through on to the landing we put pans on the stairs to collect the water and some American guests thought it was a fantastic touch.

They had only seen anything like it in English sitcoms.

Sue Gardner, who runs The Wrinkled Stocking Tea Room, declared: We've never been busier. The Bronte Sisters have been gone a lot longer than Nora and Compo but people still visit their home at Howarth.
