What function does this serve in a Christian church service? Oh yeah, it brings lots of people to church when you have your band play a secular pop song. At least this band is really good: the lady is a great singer and percussionist, and what talented musicians (listen to the lead guitarist blasting away!); but this is a TOTAL DISTRACTION from the GOSPEL!!!
