Okay, I've seen the lip sync battles that are popular on social media, but nothing beats the real thing. Check out this duet from Boston singing 'God Bless America' in perfect harmony.

They are calling it 'Cop Pool Karaoke' and it brought tears to my eyes.

According to CBS Boston, Officers Kim Tavares and Stephen McNulty put this together to celebrate July 4 and show a different side of police.

Although they've performed individually for the department, this is the first time they sang together.

I'd say it is a smashing success and is a perfect way to celebrate Independence Day. Thank you officers, for all you do!
