I don't have anything against legacy tour and people who want to see it, if it comes round again I'm going too. But the thing is there is a bigger picture, the time is running out, Forostar is correct, Nicko will be in his latter 70s and others will be approaching 70.
There is a grim possibility seldom anyone is talking about, and that is the prospect of a final album. Maiden has to stop eventually, as a touring band, the only thing it ever was. That stop will come in 2020s, we are in that decade, Maiden might continue with some sort of output, but there is going to be that last album that's all 100% new material with proper release and world tour.
