i've seen it. it's pretty cool. it's been showing at film festivals and winning awards and such. i think they are not getting a distributor at this point (it's a documentary - and they are notoriously hard to get distribution on) and are going to dvd. it'll be a two-disk set - one disk will be the film, the other disk will be all the existing performance footage of the mc5 the film makers could find. it fact, it may be all that exists.
anyway, it'll be out very soon.
