Yep, when I first started going out 10 years ago we used to start over at Marleys then onto T-Bar (toffs) then up the stairs accross town to Bentleys, O Neills, then the lounge, cafe manyana (i think thats what it was called), Blakeys and then back over to the cav.
Now there is nothing over where Cav etc was and it has slowly killed it off. If it was just to do with the population then surely Preston and Burnley would have died a death as well?
When Blackburn started declining badly a few years back I thought a walkabout or even a revolution may have kicked some life back into it but it's too late now I think.
