People are confusing things...
Rorhf wasn't about Ds coming back and mk letting his solo career apart.
It was just one off and then come back to mk solo career.
A one off.
ONE.
And that's all.
No. Here in Russia we have a sarcastic saying that goes like "Один раз — не *******", which basically means "One time does not make you a homo***ual". It's being used when you make something very bad, but for "just one time". If he would resurrect DS it would start off an enormous amount of controversy, requests, chances for an album, speculating, etc, especially after "one off" performance on on an event like HOF which is not a huge charity event like Live8 or LiveAid. Which means more fame based around DS, which is what Mark doesn't want obviously. From every perspective, marketing-wise, fan-wise, whoever-wise resurrecting DS is a bad decision and by any means never cheapens their LEGACY, please excuse the term.
