France declared that the show must go on yesterday, with the public urged to go back out to bars, concerts and restaurants in defiance of the terror attacks on Paris.

Culture minister Fleur Pellerin said musicians would "never stop putting on concerts" and claimed that in the face of "barbarism... culture is our biggest shield and our artists our best weapon".

Pellerin said the government was preparing a special fund to help get live entertainment up and running again and to aid with the cost of new security measures.

"French people will not stop going to concerts and sharing these moments of joy together which bind us all together," she said.

All major concerts, including a show by the rock group U2, were cancelled in the aftermath of the attack, but Paris' two biggest venues said they planned to reopen Tuesday.

US star Prince cancelled his entire European tour -- due to include dates in Vienna, Britain, Sweden and Paris -- "in light of the tragic events", the Interconcerts ticket company said.

"We have to turn the lights back on," Alexandre Cammas of the trendy Fooding guide told AFP, as made he made a plea with Parisians to return to cafes, restaurants and entertainment venues as the city's museums and concert halls began to reopen Monday.

Almost all of those who died beyond the Bataclan were shot on cafe terraces and the French government at first urged people to stay indoors with one suspect still on the run.

With newspaper headlines proclaiming France was at war with the terrorists -- and clearly mindful of Napoleon's maxim that an "army marches on its stomach" -- the guide called on people to go out and eat and drink on Tuesday night so "that which makes FranceFrance should not be betrayed by our fears".

"Our objective is that on Tuesday evening people return to the bistros below their apartments," Cammas said after launching the Twitter hashtag #tousaubistrot (Everyone to the bistro).
