entry isnt total free, you have to enter competitions. i believe its a few pounds per phone call, and with the number of people calling, and calling more then once, a shit load will end up being donated.
and then there is everything that will be sold at the gig, which you would expect profits to go to charity, eg merch and food.
i was also talking generally about this kinda thing. example that single that was released at christmas. instead of bono etc giving a few million, which im sure he coudl afford, they make the masses, many of whom would already be struggling financially buy the cd, with donations going to poverty.
furthermore my point was companies that do this 5cents goes to blah blah blah shit are just decieving the public. im sure more (or just as much) money could be made from the extra sales generated from this schemes then the companies themselves donate. ineffect meaning the public donates the money and the companies take the credit. my point is if a company or well off person wants to do something to end poverty why not just give the money themselves.
