I am not really sure what to say, but I think this is kind of awesome. Someone took California Love and decided to re-mix it into a tribute to Jarryd Hayne. danknerd49 pointed out a shortened version in the FanShots, and Jennifer Chan tweeted this full length version from Facebook. There's a YouTube version as well, but this Facebook version has better audio.
I am not surprised people are going a little nutty with this, but it's awesome nonetheless. Hayne seems like more and more of a strong roster option, and if he does end up on the 49ers roster, this is only going to go into overdrive.
