In this screenshot you can see that Funk Soul Brother is featured at the top of the related list.

Nowhere in the tags, comments or description on this page are those words written, but Dylan Moran in the video says them as you can see from the subtitles. The subs are also part of the uploaded video file, and not separate subtitle file/video plug in, and as such can't be turned off or on from the Closed Captions menu

Would be a smart use of http://labs.google.com/gaudi, and a nice coincidence:

<<Today, YouTube takes a fairly rudimentary approach to surfacing new videos. Watch one video about Van Halen and YouTube will recommend a dozen other similar clips featuring the rock band. But “at some point you don’t want to see any more Van Halen videos,” said Hunter Walk, a director of product management at YouTube. “You get Van Halen fatigue.”

So Walk and his team are now trying to figure out how to find new topics to engage users, a process he calls “manufacturing spontaneity.” The “serendipity of YouTube,” he said, is to show people a “selection of videos you didn’t intend to see but are very compatible. I didn’t come here to watch this. But somehow I find myself watching 10 videos about topic blah.”

To accomplish that, YouTube has begun trying to predict what topics will pique a user’s interest after they’re done watching a certain video based on data about their viewing behaviors and the content of what they’re watching. For the Van Halen user, maybe it’s something about scuba diving. Walk says some live experiments have been “very promising”.>>
