Did you look at YouTube Analytics? It should give you some idea in the Traffic Sources report.
Apparently 81% of views was suggested video, spiked around April 14th, 2012 up to a peak around July 22nd, 2012 then plummeted. But it spiked again but not as much around January 16th, 2013 through March 16th then plummeted to standard levels again. Also, the video is only 3 and a half minutes long with a retention of 47%.
