If you're into silverchair and are a big fan, then you probably know that Daniel has a younger 18 year old brother named Heath.  Heath Johns is in his own band named "Army of Prawns".  Ironically he's the singer.  It's a 3 piece band; Richard : drummer, Owen: bassist, Heath : singer; and no guitar! 

My friend showed me a picture she found of "Army of Prawns" on an anonymous web page.  When I first saw the photo I thought that it was Daniel Johns, but I was shocked to find out that it was his brother Heath.  "Army of Prawns" have been together since February of 1998.
