When Madonna does a concert, particularly if it is booked out, or nearly booked out, I suggest that there be the option to view the concert via video hook up, either at a football stadium and/or nearby movie theaters.
For example, in relation to the Australian tour in 2016, this might apply if Madonna appears in Sydney, but not Canberra.
For the Canadian tour in 2015, this might apply if she appears in Edmonton but not Calgary.
The ticket prices might be the same as the lowest priced tickets for the live event, so as not to discourage people from attending the live event if they are able to.
In the case of movie theaters, 3D technology might be utilized.
In the case of football stadiums, many of them already have large video screens installed.
