Boston Cops Sing Duet in Car, Get Brad Paisley's Attention

It's not ALL about catching bad guys.  There's fun and camaraderie on the job as a cop, too.  These 2 seems to have teamwork and harmony down pat.  Here's their off the cuff rendition of "God Bless America" that went viral last week and was even seen by country superstar Brad Paisley.  He was so impressed, he invited them to sing with him at his show next month in Beantown.
