They should try a billboard as someone reported seeing in Madison, WI!
The National Concert Hall have on street Billboard sites located near the concert hall which may well be used to advertise Hayley's concert. The sun is shining, I may take a cycle down and have a look around.
There are still a few positions along the front of the concert hall used for banners and posters, Hayley is not on any of them at the moment.
There were other poster frames along the Hatch Street Upper side, on the railings of the Iveagh Gardens and the end of the concert hall complex of buildings, but they have been removed. I do remember seeing Hayley in one of them prior to one of her previous concerts.
Uh... River of Dreams and Treasure are almost a decade ago now...
I would say use the Hushabye photo, since it is the most recent, and it is a very lovely photo and more true to her hair color now. Do the looks on her old CDs represent Hayley as she is now? Not really.
Hope you all have a great time and if possible after the show see if you can get Hayley to give you more info about the next album. I'm sure you guys have ways of making her talk ! Got any thumbscrews, Comet ?! No, just kidding !
