premise: "(Baby) You Don't Have to Tell Me" (often written "You Don't Have to Tell Me") is a song by New York songwriter Pete Antell (formerly of the American pop group The Chants) and first recorded bysinger Bobby Coleman. The obscure song was later recorded and released by the American pop group the Walker Brothers as their sixth single in 1966. The accompaniment was directed by Reg Guest.
hypothesis: The Walker Brothers released six singles before You Don't Have to Tell me.
reason: You Don't Have to Tell Me was the Walker Brother's sixth single; that means only five could have been released before.
