Aloha !

Of your five requests, Jon might give I Believe or (It's Hard) Letting You Go an outing, but as for the rest they'll need to rehearse those. All you've got to do is hand out multiple (as in about 20) banners of the same song to everyone around you. Once the band is close to you raise them all at once and the band will notice. It's then still up to Jon if he's willing to give it a shot.

Salaam Aleikum,
Sebastiaan
