I was reading of one of those inspirational magazines the other day at the doctor's office (that's where I catch up on fashion, home-making tips and anything else that I'm usually not too much interested in). In the section of uplifting quotes they had one that sounded familiar:
"When you sing, you pray twice." Johnny Cash.
I'm not denying that Johnny Cash may have said this, but the original quotation reaches far, far back. To Saint Augustine.
