There should be an annual award for most abused demo song at Audio shows. Ye with long memories will remember such cult classics as "Switched on Bach" (played ad nauseum when the ARC 3 preamp and original Magneplanar tympani's first appeared circa 1973) or Cat Stevens "Peace Train"; Elton John's "Take me to your pilot"; The Kodo drummers; Radka Toneff's ""Moon is a harsh mistress", the list goes on.
