WATCH: Old Firm Casuals, Quakes release "Never Say Die" music video

This Sunday brings the third California Clasico match-up of the MLS regular season this year, with the LA Galaxy hosting the San Jose Earthquakes at StubHub Center on Sunday, Aug. 27 (7 pm ET, FS1 and Fox Deportes in US, MLS LIVE in Canada).

It's a match-up that's provided plenty of heated and bizarre moments -- vote on your favorite here! -- and plenty of colorful banter.

A little earlier this year, we caught up with Lars Frederiksen, founder of the punk bands Rancid, and, more recently, the Old Firm Casuals, in the Bay Area. A diehard Quakes fan since school age, he wrote the team an official anthem, "Never Say Die."

Today, the Quakes and the Old Firm Casuals released the official video for the song in advance of Sunday's match. Check it out -- and learn more about Frederiksen's Quakes fandom in our previous interview with him.
