There was a whole hour of Long John Baldry (and a whole hour of John Mayall) as a separate film. Alexis Korner's contribution was recognised nicely but not enough, I thought, but the country blues/ folk blues scene didn't get mentioned at all. Maybe there's simply no film of people like Jo Ann Kelly, Mike Cooper or even Duster Bennett but to omit them and include Jethro Tull (!) extensively was bordering on the bizarre.
