Hi Greg, Ale here
I know for sure that the italian TV station RAI filmed in Feb. 1984 both performances of Queen in "Festival di San Remo" in which they played (mimed) Radio Ga Ga.
And they also filmed "Tear It Up" from the first night at the "Palazzetto dello Sport" in Milan, on 14th Sept. 1984 during the WORKS Tour.
This is what was shown on TV the day after, but I don't know if they filmed more and shown only "Tear It Up".
Probably they wont be allowe to film more of that concert but I'm not sure. So, maybe, there is a chance...
Sorry, not so many informations but this is what I know FOR SURE
