“My Boyfriend’s Back” is still funny as hell in 2020; I don’t know if it’s the sharp writing, Peggy Santiglia's snotty proto-Kim-Deal delivery, or both. Nancy Sinatra’s “Boots” likewise exudes self-possession, walking the line between ice cold and fiery hot; even Lesley Gore is winning as she fails to keep herself together. It’s hashtag relatable. All these 60s megahits remain soundtrack and radio staples for a reason; the alchemy of a perfect song and just the right singer can endure for eternity.
