Not everything they did, but they got it right on this track which even found grace with its original composer Aaron Copland in the version they did. And playing at below zero temperatures in an empty stadium of course sums up ELP's testosterone-charged megalomania (which was both awesome and laughable at the same time) nicely.
When I first saw that vid sometime in the seventies I thought it was
the essence of rockstardom.
The desolate vastness of the stadium, their visible exhaled breath, the leather jackets and fur collars plus the controlled racket only three men made - all very impressive!
