Defao could bring the whole band to Europe. It's the tour-promoter task to decide how many musicians to bring, because it's not his money and it's very expensive to bring alot musicians. Back in the days the most band were only bringing 4 singers, 3 guitarist (1 lead, 1 rhyhm, 1 bass), 1 drummer, 1 atalaku and a percussionist. I think also that Defao knew and was fearing on the same that some musicians would leave. Which also happened the whole band stayed in Europe hahahahaha. So he had to recruit a new guitartists and some singers.
