I would be happy with ten Gers/Harris' but as long as there's two I take it. Its gonna be a decent album no matter who get the credits, which you can always expect from Maiden. Even their worst album is better than 60% of recorded albums in history.
If Murray manages to redeem himself I cross my fingers for his 4th good song after reunion. But don't bother with mediocrity. Smith / Dickinson is overrated but I guess we could do with one, or put 'Arry in the mix and try to repeat AMOLAD writing sessions. Maybe one Smith / Harris. Naturally there is no Maiden album without 2-3 Harris epics / solos.
As its their finaal album I hope one extraordinary surprise like Murray / Dickinson, Gers / Dickinson, Harris / Dickinson. Or Smith alone for the first time since SIT.
