Worship Central is a worship ministry led mainly by Tim Hughes. They regularly hold events around the world and on February 11th, 2012, they came to Paris for the first time. (This worship night was organized by Alpha Jeunes)
It was awesome to be able to worship God with so many people (700 ?) and in English with one of my favourite Christian singer.
Happy Day is one of my favourite song. I recommend it especially in the morning.
