Repartee, involving witty comments, often rapidly dispensed and the Raconteur, replete with funny stories and accounts, able to amuse after some typically convoluted and involved dialogue, is not especially unique to Manchester
It is probably more a case of the common social conditions and shared understanding, or experience in the community, that enables the comedians of the North West to 'work the crowd' in clubs and variety halls ?
Possibly there is also a greater sense of togetherness in the interconnected regions of the 'dark, satanic mills' and an ability to laugh together, in spite of and because of our heritage ?
This coupled with the endearing and very personable human characters i.e. the loveable personality of some of the comedians we can identify with, helps to keep the humour of the N.W. of England unique and worth preseving, amongst the efforts of other indigenous communities ?
In other words, I tend to think our rich and vibrant heritage is more important to our humour than the art of humour for it's own sake alone !!
Not just Manchester, but Liverpool also is not without its valuable contribution.....
