Getting LB to sign BN at concert question

[Lauren]

Hey all!
I am seeing FM on Sunday in Denver and I have very good close seats near LB - so my question is I am bringing my BN album and hope I can get a signature - for those with luck with this or even with suggestions when is a good time to hand it to him? (Like does anyone know when there's a short break, etc.) I want the timing to be good of course! Gotta get me a sharpie!

Thanks!
Lauren
