Sean's guitar

[cherrybomb]

I heard, or read an interview with James a while before the album was released where he said that he couldn't come up with a guitar part for a particular song so Sean played on it instead and came up with something better than James ever could which really pissed him off. Can't find the interview anywhere now, does anyone else remember this? And which track would it be? The fact that the demo of Let's Go To War has no guitar line leads me to think that it may be that, anyone know for sure?
