one important thing is that Jon doesn't pay attention WHO ASK AND FOR WHEN he sees a request and sometimes do the sogns but with a delay ..... you ask for STBI they will do it the next show or the next of the next (they MAY do it ) ....so to get what you want 'for sure' the best is to have 3 shows in a row

..... rare are the times they will truly play something spontaneous (not prepared) the latest examples are it's hard letting you go at the last O2 show and lie to me in bristol in 2008 he did it seing the banners THAT DAY but it is risky ...
I think to have good chance we have to stick all together and not be too demanding... you request 2 songs once you get them you request the 2 next ....
well in 2003 laura and taija had a list of the songs they wanted to heard jon picked them among the list posted first row (that was the era where the fans were for sure in the front pit ... this tour we have no clue ) they checked each song requested played ....
if you are able to do a lot of shows you will get all the best chances your way ...
