What's your first thought if you heard that a police officer covered Johnny Cash's Folsom Prison Blues? Irony comes to mind.

But for San Antonio police officer Billy Morgan, it is just a great performance.

Yeah, that's pretty darn good.

Officer Alex Garza is the one who recorded the video according to countrythangdaily.com. He was asked "why this song"?

I know it’s a song about going to prison, but it’s one of my favorite Johnny Cash songs.

He also said he wanted to show another side of police officers outside of the badge.

Sure enough, as soon as he started singing, he blew us all away with his voice. I posted the video on Facebook because I thought he could bring a positive reflection on police, to show people that we have hobbies outside of policing.
