Brian and Roger are jealous of John's success with the Man from the Shadows album. They're pissed that he didn't write songs like "Fist through the Window" for a Queen album, but for his own solo projects. After the huge success of MFTS and the relative flop of recent Brian/Roger projects... Let's just say they're not on speaking terms anymore.
Pim, please get your classics right! The name of John's solo-album is of course "Man IN The Shadows". Let's give this jewel the respect it deserves, OK?
