NEW YORK (AFP): Jack Ely, whose 1963 song ‘Louie Louie’ was so unintelligible that the US government investigated it for secret messages, has died aged 71, his family said Tuesday. Ely was the 20-year-old singer of The Kingsmen when the band recorded the hard-charging song, which became a hit at the start of the rock era - even though the only clear words were in the title. The song came to the attention of FBI director J. Edgar Hoover, who was notorious for secret investigations, after the song was banned in the state of Indiana.
