Oh that's nice! Bonjour! Or I should say Salut, which is less formal

I think it'll be ok for the concert tickets because it's not his proper tour so it's not much advertised. I think only fans and people in the gig area know about Mika performing there. If it was his 'normal' tour I think you'd probably have to book months in advance

I don't know about Nice though as it's a festival, I have no idea if there are many tickets still available!
