The statement did not identify the cause of death.
According to ABKO's web site, Valentine was recruited to affix the Animals by Eric Burdon, Chas Chandler and Alan Price in 1963.
In 1994, the original group was inducted into the Rock and Roll Hall of Fame. "Here was a guy with the greased mop of hair combed back, cheap leather jacket, winkle picker shoes, black jeans and a smile on his face playing through an echoplex, which was a secret weapon back then", Burdon told the magazine.
Some of the band's other hits included Don't Let Me Be Misunderstood, and We Gotta Get Out of This Place, which was adopted by many United States soldiers as an anthem during the Vietnam War.
While the band's first USA single "Baby Let Me Take You Home" barely dented the charts, its followup, a hypnotically bluesy rendition of the folk classic "The House of the Rising Sun" spent three weeks atop the Billboard Hot 100.
"The opening opus of Rising Sun will never sound the same!". You didn't simply play it, you lived it!
Despite leaving the band in 1966, Hilton remained close friends with members of the group, and released the solo record All In Your Head in 1969. Heartbroken by the sudden news of Hilton's passing.
Most recently, Valentine returned to his first love of skiffle music, forming the band Skiffledog and releasing two albums. We had nice instances collectively, Geordie lad.
Valentine took up the guitar at 13 in his hometown of North Shields in northeast England, subsequently getting involved in the skiffle craze - a kind of fusion of American folk, country, jazz and blues - that was sweeping the U.K. His skiffle band The Heppers evolved into The Wildcats, a rock and roll band that became popular across the north of England, partly because of Valentine's habit of rolling on the ground while playing his guitar.
