I wondered what was so special about this bootleg. When I listened to it, I thought that all the songs were sung by Freddie when he was 38-40 years. So his voice is much more mature than his voice in the 70's. Is it true or is it just my imagination?
Nothing too special other than it collects together some very good sources of individual songs. I bought a copy in the late 1990s and ended up getting rid of it simply because the accompanying booklet was so poor. Also, there was too much of a relaince on Tokyo 1985 (the worst sound Queen ever produced live) for my liking.
You're better off getting a track list, downloading the material from elsewhere and making your own box set. There is better source material available now as well.
