Living in England and a fan from 69 - 77 I've purchased the blu ray version of the above. Although promoting democracy the documentary highlights the drivers of the early days Robert Lamm and Terry Kath.Robert's song book appears in the early days with so many great songs it just confirms that Robert with TK were the drivers. It's a poignant tale superbly put together with some rare footage of the early days when the band were naive and still aiming high.
The abundance of great songs from Robert's book is jaw-dropping.
One of the highlights was Robert barely hiding his dismay & dislike of 'If You Leave Me Now' - hilarious.
Essential for all fans, just waiting for the TK film now to complete the story.
