“River Deep – Mountain High”  is a 1966 single performed by Tina Turner and credited to Ike & Tina Turner.  Written by Spector, Jeff Barry, and Ellie Greenwich, and considered by producer Phil Spector to be his best work, the single was successful in Europe, peaking at number 3 in the United Kingdom, and peaking at number 16 in Australia though it flopped on its original release in the United States.  After Eric Burdon and the Animals covered the song in 1968, it was re-released a year later, and has since become one of Tina Turner’s signature songs, though it charted even lower, “bubbling under” at number 112.  In 1999, “River Deep – Mountain High” was inducted in the Grammy Hall of Fame.  (More from Wikipedia)
