No Riff?

[Joda]

I just bought Swing parade as VOD, and downloaded it, but I'm confused as to why there is no riff. It says on the store page that Mike is commenting it, but, in the first 20 minutes and the segments I watched fast-forwarding, there were no comments. Can anyone tell me if I for some weird reason have been given the unriffed version, or if the movie does not have a riff?

Thanks in advance.
