We all have our own ideas of how a song should be, because, I mean, a song can be done in so many different ways, depending on who's doing it, but sometimes I just feel it's not right, like in case of Roger's track, which is Magic, he did it in a totally different way, which is quite good, but I just felt that there was another commercial streak and I just realised that he was going away to LA for about a week, so I just got hold of it, and I just changed it around completely, and when he came back, I said, “well, what d'you think?” And he said, “oh, I like it!” It's a completely different song, but sometimes you can see something else in other people's songs, and I don't mind them do that to my songs. We all help each other in away, but that's what then takes a lot of time.
