I agree that the thing to know here is whether you are actually getting involved in a "Christian Band" or a band with Christians in it. Of course, if the song writer is a Christian, they can't help but write from that perspective, but it doesn't necessarily mean you need to be "on message" with them.. unless you decide you want to be, which is great.
Of course it will help if you have some basic understanding and acceptance of the content of the music/lyrics so that you don't come across as being an outsider or something, but look at U2 - they were basically playing Christian music from the get-go (the 'October' album would have fit in perfectly in any Christian Music store, if there had been such a thing at that time), and all of them but their bass player were Christians. They're still together and going strong.
Having said that, if this is a band that is headed toward the Christian music industry, I would stay away. The bean counters in mainstream music are bad enough, but there is nothing worse than a bean counter who counts his beans "for the lord". Uggghhh...
