Thanks to Andertons! What I got from this interview — yes, the song is king, and yes, if you were smart enough and humble enough to acknowledge that MK is THE songwriter in the band, then you could've stayed in the band for as long as you want.
It wasn't autocracy, but it's hard to argue when presented with songs of this quality and quantity ("Mark always had something else"). Serve the song, enjoy the master doing his thing, it's a dream job, really.
Sultans Of Cringe though was not the brightest part of this interview. I wonder why they just won't let somebody play along with John's rhythm, they have amazing guitar players on board.
If I were Lee, I'd play some rhythm, give John bass guitar, and let somebody play the lead over.
