Whilst their age is certainly a factor, I feel that with a touring schedule that has four days in between each show, and travelling and staying in five-star luxury, I don't see why they couldn't do two legs next year. Perhaps the US tour being 14 shows in the Spring, finishing early June. Then, after a two month break, they could do 10 or 12 shows in the UK and Europe in August and Sept
