Punch-Up Aussie Tour Single?

Aussie CD vendor Siren Disc is listing a special Australian tour single of Punch-Up At A Wedding in their “coming soon” section. There are no details other than a release date of April 19th. We’ve yet to see this listed anywhere else, so we’ll have to consider it a rumour for now.
In addition, Siren Disc is offering the Japanese Com Lag EP as a preorder, as is Amazon Japan (you’ll need to translate the page if you’re not up on your Japanese).
