It is certainly true that The Beatles put on a bad show during the height of their popularity, through no fault of their own. They invented stadium rock. They relied on the venues to provide the sound systems; they toured only with their three amps, instruments and drums. The stadiums used rinky-dink sound systems with little speaker columns arrayed along the first-base and third-base lines. So The Beatles performed from a stage over second base with their amps cranked up, and with no stage monitors. They could hear only their amps behind them and constant screaming of fans in front of them. At Crosley Field, the management didn't even plan for rain. Fortunately, The Beatles called off their portion of the concert before been electrocuted and played the next day in the early afternoon with the rain gone -- but now a tarp cover unnecessarily in place.
