Roger Waters is featured in a segment of CBS Sunday Morning(6/4). During it, the Pink Floyd veteran tells the program's Anthony Mason while talking about his current tour, 'I can't imagine I'll ever do another one after this.' This comes as Waters and David Gilmour have come to terms with past differences that caused each to take pot-shots through the press and social media at one another. Of those skirmishes Waters says it's '...a real waste of time and energy to butt heads about things that are essentially superficial.' Whether the cease fire opens up the possibility that Waters, Gilmour and Nick Mason will ever share a stage together is anybody's guess.
