The Beatles "Oh! Darling" from the vinyl LP 'Abbey Road', Apple records, released in the US, Oct1969. Composed by John Lennon & Paul McCartney (really by McCartney, despite the long-standing joint songwriting credit).
John Lennon wanted to sing "Oh! Darling" thinking he could do a better job than Paul -- but for over 40 years, I believe the record shows that McCartney did just fine.
