I was big into Delirious? and have recently got back into a couple of their older albums (Glo and a Deeper). They had a real influence on British Christian music and there are now a number of blatant pretenders (Tim Hughes for one!).
From a Catholic viewpoint, at the end of the 90’s I read an article in which they explained how they had discovered that Catholics could be Christians too! They were honest in admitting that they’d been brought up with a default suspicion of Catholicism, but having met a Catholic community near London, they were disabused of this view.
For those who don’t know, their album Glo, opens with the monks of Ampleforth Abbey, Yorkshire, belting out “God you are my God” - makes the hairs on the back of your neck stand on end!
