OK, more British Invasion: Graham Gouldman (subsequently of 10cc) wrote this song about lost love in '66. Masterfully alternates between mournful minor-chord verses and an upbeat chorus in majors. Peaked at #7 in the UK - released in the US as the B-side to "There's A Kind Of Hush" (#4) reaching #35 in '67. 1st Herman's Hermits' recording with full orchestra. Quoting Peter Noone: "...Herman's Hermits' best recording".
Yesterday's answer: "How High the Moon". I had the distinct privilege of seeing Les Paul (at the tender age of 87) with his trio at the Iridium Jazz Club in Manhattan some years ago. He played there every Monday since 1994 until his death at 94! INCREDIBLE! He played "Brazil", "Caravan", you name it - as fast as when he was in his prime.
