Dan: It must have been incredibly emotional for you guys... N: Yeah it was, watching him out there ... first of all, that's a tough song to sing and being out there on your own for the first time on the week that something like that happens must have been horrific for him. But it was a no brainer, we were all in America at the time, I remember I was in NY and I heard about it, there was no doubt that was the next thing I was doing. ... So we all flew home and we didn't want it to be like a whole publicity thing ... Dan:... No pictures N: No we didn't want that, we were just in and out, seeing Louis for what it was and just be there to support him cause it is a tough time you know

Oh yeah, big email chains are going on all the time. Everyone's like trying to listen to each other's stuff. Louis lives quite near me in LA so I'll be going to his, when I get out there. He's basically there all the time now, in and out of the studio and stuff so I'll be seeing him,  and playing him some of my stuff and hopefully he's got some stuff to play and same with Harry. I think Harry is out there for Corden that week so I'll try and bump into him too

“When it will be, I don’t know. I ­prefer not to do it after I’m 40. I’d prefer the next few years.”

To be honest I don't know the answer to that one, I'm guessing so. You know the fanbase is strong and powerful, as you know,... but that's not a coversation that we've had... and hopefully wont
