It simply went on for too long.
I justified it as being the affirmation of the end of Freddie Mercury being "in" Queen - remember rack 13 is the surviving member's take on what Fred's journey to heaven may have "sounded".
That then led to Paul's plea to the crowd that he was / is "reaching out" for our support in this venture.
And then literally knocking us over with TYMD.
All that said, Track 13 was fucking boring on the MIH album - I remember feeling cheated that they had left THAT MUCH space on a £15 CD when it could have been filled with the Headbanger's Mix of HTF, I Go Crazy and anything else they hadn't issued before.
The lights were off in Brixton for the whole of Track 13 and NOTHING Happened - maybe if they's had a video presentation to accompany it or something?
Or, simply, just come on stage a LOT earlier than they did and added a coupleof other songs.........
Still, I'd forgotten all about it by the time I'd started clapping them off stage for the last time.
