Some people are saying it’s time we swapped some players on our team.

Changed our local heroes, our Naana and Daada. Boulton and Watt, they say, are just not cut out for the 21st century.

They need to get back to the pavilion, we’re told.

Well, they’ve had a good game; a combined innings of 164 years, then 200 years of obscurity before hitting the big time again; biographies, exhibitions; celebrity status.

But Boulton and Watt were manufacturers, after all, and we’re being told Birmingham won’t be needing any more industrialists.

Could it be our Lunar legends just aren’t working their magic any more?

Birmingham; it’s the ugliest and dullest city, says Trip Advisor.

Birmingham: facing something of a crisis, says Lord Adonis.

Can our heroes’ examples lively us up to Birmingham’s new challenges?

Anyone who’s lived, worked, shopped or drunk in Handsworth has to be amazed and inspired by the Lunar legacy.

Steam engines. Coins. Inventions. International ambassadors. Entrepreneurial zeal.

But Boulton’s revolutionary Soho Manufactory has left almost no trace today, a tragic blueprint for Birmingham’s vanishing industrial heritage: Bournville, Longbridge, Rover, Aston Cross.
