I don’t know, maybe you could have a French Pop Diva Tour. Get Alizée, Yelle, Natasha St. Pier and a few more together. Possible other candidates could be Jenifer, Lorie, Nolwenn Leroy and Amel Bent. Each could perform 3 or 4 songs of their own and then do a few songs together. They could also perform some English standards. Like a mini Les Enfoirés.
They could even film a concert in France and get it shown on PBS, just like they did with “Riverdance” or “Celtic Woman”. Then follow that up with a US tour. It might be easier to promote something like that.
OK, I admit it. I’ve probably gone off the deep end...
