tennis fans face a wimbledon-type scramble for davis cup quarter-final tickets this summer .
there will be a capacity of 7,000 for july 's match against france at london 's queen 's club , but well under 3,000 tickets may be available to the kind of supporters who created such an electric atmosphere in glasgow for last month 's first round .
the rest will go to various organisations and governing bodies , with a considerable percentage going to well-heeled queen 's members will also have a considerable allocation .
