OK, more 60's: This Medley/Russell composition was first recorded in '61 by The Top Notes - produced by Phil Spector. The Isley Brothers' '62 version was a Top 20 hit in both Pop and R&B. The Beatles' rendition in '64 with Lennon on lead vocals reached #1 on Cashbox. Highly evocative of Ritchie Valens' '58 "La Bamba". Featured in "Ferris Bueller's Day Off" and Rodney Dangerfield's "Back To School".
Yesterday's answer: "Luka" by Suzanne Vega. Incredible song - even after all this years it still tears me apart every time I hear it.
