I wonder if Louie Louie was the only song to have gotten its very own FBI file .The file was 119 pages long according to the BBC this morning:
"The early rock and roll song Louie Louie by the Kingsmen, for instance, was the subject of a 119-page file. The lyrics, written in a quasi-Caribbean metre, are famously difficult to discern.
Some, including an official at a Florida high school and Indiana Governor Matthew Welsh, suspected the words were secretly obscene, and the FBI launched an investigation.
"The laboratory is requested to determine if enclosed record Louie Louie can be considered obscene for purposes of prosecution," an agent wrote in the file "
