Mirko Filipovic makes sweet music with Pat Barry outside of the cage

Fans only moderately familiar with Mirko Filipovic may view the PRIDE icon as a cold-blooded kickboxing machine given the no-nonsense look he wears on his face from beginning to end on fight night. That being said, outside of the ring “Cro Cop” is actually known for having an incredible sense of humor and being somewhat of a prankster.

Comparably, fellow UFC heavyweight Pat Barry has never been accused of taking life too seriously and might be mistakenly seen by some as only having an arsenal of devastating kicks at his disposal in common with Filipovic.

Barry: “Sometimes You’re Just Gonna Get Hit.”

Once opponents in the Octagon, Barry and Filipovic have since developed a friendship based on their kindred spirits including some time training together as “Cro Cop” prepares for his bout at UFC 137 against Ultimate Fighter 10 winner Roy Nelson, a match-up possibly marking the final fight of the 37-year old’s storied career.

The two stand-up specialists recently gave MMA fans a peek into some of the time they’ve spent together. However, rather than the video focusing on time hitting pads, Barry and Filipovic work on hitting high-notes as they sing along to “California Dreamin’” by The Mamas and the Papas.
