Samuraisan; I know for certain that we have seen the concert several times but there is no 'R' denoting Repeat in the tv listings for either the concert or the documentary. I would hazard a guess that anything that concerns Freddie has already been seen at least once since his death.
To true Ken. I looked on my app Tv24.co.uk ( we are not in the uk but get all the programs ) and it says it was broadcast in 2012. Never mind though, there's nothing else on except for Eurovision's greatest hits.
