I checked this out and it was pretty good. Agreed with much of it, not all and a few innocent errors (they all sang), but it was well done and from someone that had first hand contact with the band and especially Freddie. Thanks for the link.
To be fair on stage they did all sing, John even had his mic at a decent volume until until 1977, then they realised what John actually sounded like and started mixing his mic really low.
