Jack Ely (third from left) with The Kingsmen, circa 1966

The singer of the 1963 classic single Louie Louie has died at the age of 71.

Jack Ely died at his home in Redmond, Oregon, on Monday morning (27 April).

He was best known for covering Richard Berry's Louie Louie with his band, The Kingsmen.

Although the FBI investigated the famous track over fears the lyrics could be obscene, investigators later concluded they could not even hear it as it was "unintelligible at any speed".

His son Sean said his father was content to be a one-hit wonder and later became a horse trainer in Oregon.

"He wanted to try on different occasions to pursue other endeavours in the music industry, but I think when it was all done and said he was pretty happy that he did Louie Louie."

He added the cause of his father's death remains unclear, even to him "because of his religious beliefs, we're not even sure what (the illness) was".
