John Lennon, when asked why he would never re-form The Beatles, said "It wouldn't be The Beatles, it would be four guys who used to be The Beatles." That is from a man with the sense of dignity to let his legend stand, and not degrade it with a re-run.
Axl Rose has no such concience. What you will see won't be 'Guns 'n' Roses', it will be the guy who used to be the lead singer with Guns 'n' Roses, and a few anonymous session musicians, doing record-perfect run-throughs of the band'* ****.
My avice? Stay at home, play your albums, remember them as they used to be, steer clear of the Axl Ego Show, it's embarassing.
