Out of curiosity, I checked to see where this song reached on Billboard. It got to #5 in 1966. Released late '65 as a B-side, and January '66 as an A-side, demonstrating once again @MarkB 's assertion that B-sides are often more interesting. I probably heard it in 1966, so I may have been 9 years old if I heard it in the summer, as my birthday is in March.
