Do You Rekon That Ae, Trivium Or Machine Head Will Sign at the black crusade in syd

as in signing sesh afterwards ?
I went to the Perth show on sunday night, there wasn't any signing sessions.
But it was a great show and they had some awesome shirts for sale for 40 - 60 bux.
there better be a signing session when they come to brisbane
Nothing makes you feel more alive than flinching when your toast is ready.
you'd think for sydney that Utopia would hold a signing, they usually do for most bands.
