Whether the shows are more or less powerful/energetic/frenetic/exciting and so and is up for debate (read a dictionary definition before arguing certain peeps ), and they did 4 tours for marginally more than 2 tours for U2 in your example, but they have been prolific with the stuff post '00.

Not showing any real signs of slowing, with rumours of Greatest Hits/Studio record/Richie solo effort. Yay 'n' al' that
