First recorded by Paper Dolls (1968).
Hit version by Jefferson (US #23/MOR #19/CAN #15 1969).
From the wiki: “Paper Dolls was founded in 1967 as a British female vocal trio from Northampton, UK, who appeared a couple of decades before similar all-girl recording acts, such as Bananarama, Atomic Kitten and Spice Girls, became commonplace. Pre-dating the Spice Girls, each member of the girl group had a nickname (Susanne Mathis, ‘Tiger’; Susan Marshall, ‘Copper’; Pauline Bennett, ‘Spyder’).
“Signed to Pye Records, Paper Dolls had one solitary chart success: The song, ‘Something Here in My Heart (Keeps A Tellin’ Me No)’, written by Tony Macaulay and John Macleod, was their debut single. It reached #11 on the UK Singles Chart in 1968. The group’s greatest professional disappointment came when their producers first arranged for them to record another Macaulay co-composition, ‘Build Me Up Buttercup’, in 1967. But, due to a misunderstanding, Paper Dolls never turned up for the session; instead, the song was given to The Foundations, whose version became a transatlantic hit.
