In what they say is a last-ditch attempt to save Britain's pork industry, dozens of pig farmers gathered in London Thursday aiming for an Internet hit with their song 'Stand by your Ham.'

The song, which reworks Tammy Wynette's 'Stand by Your Man' with a porcine theme, is intended to alert the public to a sector that farmers say is being pushed to extinction by greedy supermarket chains and rising feed prices.

'Stand by your ham,' runs the chorus. 'Sausages, pork and bacon/Help us stay in business/Because our pigs are worth it/Stand by your ham.'

With little singing experience but fuelled by enthusiasm and bacon sandwiches, the 20 to 30 farmers hope to rely on affection for traditional British pork products from pies to sausages.

It will be available for download from the weekend from the website www.pigsareworthit.com.
