Nobody knows for sure what is going on with AC/DC. The Sydney Morning Herald is reporting that founding member Malcolm Young has returned home to be with family. Lead Singer Brian Johnson told a Florida Radio station that "One of our Boys is Pretty Ill...so we don't wanna say anything we are very private about things like this". It is not clear if Malcolm is unable to perform or what the fate of the band is right now. We will have to wait to see what the future hold for the band.
