Someone stole a National Trust of Australia plaque (pictured at right) from Bon Scott’s gravesite in Fremantle, Australia, sometime between Saturday and Sunday, which would have been the former AC/DC frontman’s 60th birthday. Scott’s grave, which attracts thousands of visitors each year, may be subject to tighter security. Doug Thorncroft of the Western Australia Bon Scott Fan Club suspected the theft “was probably an alcohol-fuelled spur-of-the-moment thing.” Y’think?
