Ladders, go back to where you come from., page-33

All Australians of a certain age should get their old guitars out of storage, practice up on a couple of Dylan songs and know that they have their personal security issues sorted.
Just wander the streets with your guitar in hand (like the gormless prat in the expensive NRMA ads) and if any aggro young bearded, turban-ed bloke with a sharp blade approaches, just fix him in the eye and start into - "All you need is love - da da da da da, All you need is love - da da da da da". If he still looks threatening, give him a hug.
