In the technological and supposedly sophisticated age we live in, it isn't enough to sing, dance or tell a joke in the name of entertainment. Now people think up stuff like this:
'I know lets strap ourselves to a fancy metal frame and dangle the whole thing off a bloody great crane, throw in a trio of acrobats dangling off trapese swings and hey presto, entertainment for the 21st Century'.
It's not like you can fold the crane away and cart it around in the back of a van, which presumably limits the number of venues it can be 'performed' at.
Yes it's quite spectacular for a couple of minutes but soon neck-ache sets in. I bet the neighbouring drum and bell group are reeling at not having thought of it first.
