Trust me guys a good sign will do the trick.. mine said:
"Dear Jon, It's Almost Xmas.. I've Been A Very Good Girl This Year....
Please Play Blood on Blood!"
And he did!! AAAAHHHHHHHHHHHHHHHHHHHHHHHHHHHH!!
What song are you going to ask for? And how close are you to the front?... it helps if Jon can see it too!
GOOD LUCK!!

Fingers crossed!!
