In examining the past, some people respond with the "what ifs" and the "might have beens", trying to wish a "colorful" era or character back to life, all expressive of a dissatisfaction with the ways things have turned out. In response to a book review on blogcritics, I posted this:
After that idiotic flip out scene at Bill G's in 1977 (which is quite unpleasant just to have read and heard about at the time, violence and piggery being what it is) ...
I remember an immensely talented parody of Led Zep that was broadcast throughout the Bay Area on what was the vestigial remains of "underground" radio in 1978. A true parody, the subject was a mock of media favorites who have achieved massive and sometimes questionable popularity. This was a crossed version: The "Theme to Gilligan's Island" performed in the style of "Stairway to Heaven", but not merely imitative or sound-alike.
Led Zep's legal squad inexplicably exploded on the scene, out to (somewhat inconceivably) collect all copies of the tapes. They apparently interrogated the radio station personnel in order to uncover the source, to find and punish the parodists as well. They apparently implied they were out to search and destroy, sending out threats and warnings. Well, those tactics were ineffectual in the long run as they predictably always are.
But that seems fairly typical of Led Zep vibes. At the time, I doubted they could even so much as comprehend the cultural complexity of the parody.
