Basque song

I think I passed the test to be accepted into my choir in St Jean de Luz. Midway through practice last night I was presented with one black and one white shirt with the choir emblem on them (actually very tasteful). This was followed up by an explanation that I would be singing at two venues. I had agreed to this before I realised that one is today and the other tomorrow. We are singing nine songs, I currently know seven and have just over an hour to rehearse the others. I also have to squeeze in a flamenco class before singing. It's all go.
