"You Don't Have to Say You Love Me" (originally a 1965 Italian song by Pino Donaggio and Vito Pallavicini) was a hit for Brit singer Dusty Springfield in 1966. It was her biggest ever charting song -- #1 in the UK, #4 in the US on the Billboard Hot 100. This performance was part of a 1967 Dusty Springfield special on the BBC.

Other popular songs by Dusty included "Son of a Preacher Man," "Wishin' and Hopin'," "If You Go Away," and "The Windmills Of Your Mind."

Elvis covered "You Don't Have to Say You Love Me" and had a Billboard #11 hit with it in 1970.
