OK, back to the 30's: Written in '39 by Glenn Miller and Mitchell Parish, this ballad about two lovers spending a romantic night together was an instant phenomenon and became Miller's signature tune. It peaked at #3 and remained in the charts for 15 weeks. Inducted in to the Grammy Hall of Fame in '91. The high-leading clarinet over the sax section playing in essence two different melodies developed into "The Glenn Miller Sound". It "evolved" from Miller's '35 "Now I Lay Me Down to Weep" through "Gone With The Dawn" and "The Wind In The Trees" to its final title in '39. Classic cover by Sinatra in '65. Archie and Edith danced to it during a '72 episode.
Yesterday's answer: "Not Fade Away". Love Brian Jones' harmonica! I'll never forget the Voodoo Lounge concert in Ames - they opened with "Not Fade Away".
