did one a few months back... open air gig for several hundred Malaysians to give them a "taste of Australia"....

there were 3 of us playing... our speakers were a few metres in front of us............. and we were singing "Click go the shears".... at which point a stockman (in full "man from snowy river" gear) on his horse sent his cattledog and a small flock of sheep right across in front of us between ouselves and the speakers (followed by himself on his horse).....

very atmospheric....... and the speakers stayed up......
