How can we keep from singing?

A friend at church asked me what we were singing in Spain so I thought I would answer that question for anyone who is wondering. We are singing mostly sacred music since most of our venues are churches and they are very careful about what is performed inside. For example, when we sing in the Monastery Basilica at Montserrat, near Barcelona, we are allowed to sing 2 or 3 pieces as "an offering to the Madonna," La Moreneta, whose shrine is there. http://www.sacred-destinations.com/spain/montserrat-shrine.htm

We do have some secular music as well---Shenandoah (which we have sung on every choir trip), for example, and when appropriate we sing the OU Chant and Oklahoma. We sing several spirituals which are always a big hit in Europe. And we will be singing in English, Latin, French, and Spanish--Dr. Curtis always has us sing a few songs in the language of the country where we are. We have been known to sing in plazas and on street corners and in other impromptu places---the Pantheon, the monastery at Melk, the Eagle's Nest, Il Campo---after all how can we keep from singing?
