Very interesting!

Well put together about the Sparks ... it was great to see how the group evolved over the years and to learn of their amazing work ethics

Great to have a light-hearted documentary. Love the visual jokes.

I live with a musician and he knew who they were, but I had never heard of them. It was very interesting, but just lagged in a few places since it was 2 hours 20 minutes long. I think it has a fairly narrow audience appeal even though I enjoyed it.
