I was just wondering. I met a few of the members in my friends band. I'm playing guitar and bass for them. I know my friend Niki is catholic, but it never really mattered to me. anyway, when I met the other members, I found out that all three of them were either catholic or another branch of Christianity. it's cool with me, but it was a little awkward when we busted out the old testament looking for ideas for a band name. lol too me, the only thing that could come out of the bible worth while is something dark, brutal and metal sounding.
Yes i have been in one band in the past that was very interesting. lol both the drummer and guitarist were staunch methodists, and me, being a staunch atheist, found much disagreement. we eventually broke up.
Most singer songwriters I know are theists, well at least outwardly. I'd bet many of them are like I used to be - don't offend and go with the flow. This approach was bearable until god and country became synonomous.
