Hi Kevin...........I was there in '65 when Bjorn Knudsson had his happy hour. I too was struck by how green the grass was until I spotted some of the floodlights had a green tinge. Ok, so they cheated, but boy did it look good.
Apparently, unlike the London Bridge, the towers were built of re-inforced concrete, so taking it down piece by piece wasn't an option.
We could still have sold it to the yanks though...........if they could carry a Saturn 5 on a low loader 40 years ago, just think what they could do today!!
