The singer, Tammi Terrell, joined forces with the remarkable Marvin Gaye to create some of the greatest love songs ever to emerge from Motown, a music company that was located in Detroit, Michigan. Sadly, Marvin and Tammi had their series of classic duets -- "Ain't No Mountain High Enough," "Ain't Nothing Like the Real Thing," and "You're All I Need to Get By" among them -- come to an abrupt and tragic end with the premature death of Tammi. She died of brain cancer on March 16, 1970.
