Pink Floyd to re-form for charity?

Roger Waters is bringing his reimagined version of The Wall to Kansas City, just in time for Halloween. Could it be possible that Pink Floyd is reforming for charity, too? Despite Waters and David Gilmour’s bad blood, it seems like drummer Nick Mason thinks so. He told the BBC,
“I think it would be a very nice way for a band to gently move towards retirement, by doing shows absolutely for charity rather than for more income. In a way the best thing would be to do a number of shows and have some sort of foundation.”
