Fleetwood Mac's lovely, bittersweet 1975 song 'Landslide' provides the soundtrack to Budweiser's 2013 Super Bowl commercial, which for some reason you can see in its entirety right here and now.

In what's clearly becoming the dominant way of doing things, the beer company released the commercial for free on YouTube yesterday (Jan. 31), apparently hoping to build a viral online buzz even before the spot even shows up in its ultra-expensive spot on football's biggest night.

As Stevie Nicks sings of changes and regret and getting older, we watch a heart-tugging montage of scenes tracing the relationship of a Clydesdale (and his loving breeder) from birth up until the day the horse gets the call-up to the big leagues, parading around in front of the famous Budweiser wagon.

The spot then cuts to three years later, with the breeder traveling to the big city just to see his old friend again, and... well, we won't spoil the rest for you. It's oddly touching (if a tad unrealistic), but our favorite recent use of 'Landslide' on television is still the 2011 episode of 'South Park' where Stan falls victim to crippling cynicism.
