I just typed "Floyd Tour dates" in the search feature and ..vio-la.
Regarding future tours....alas.. with the exception of dear Roger going out solo...I fear that these "future Tours" exist only in the hopeful, yet somewhat misguided, minds of youthful fans everywhere.
Nobody will be happier than I if I'm sadly mistaken, but I beleive we have seen the last of Pink Floyd on the road.
