"One of my kids, he's 13, and now I'm getting those phone calls: trouble here, homewhere there, disappearing over there - and that's a bit of a challenge, as I now move forward to finishing a record and going on the road. It is a concern."
- Larry Mullen Jr, 2009
'40' from the War album almost was never recorded. The band (minus Adam Clayton who had left the studio) had gone over their booked studio time, but convinced the studio manager to let them record '40'. It has closed many show since. The Edge plays both electric and bass guitar on the song.
