20. "In The Summertime," Mungo Jerry
This British bubblegum blues band's 1970 guide to doing what you please is one of oldies radio's most recognizable jams thanks to its bouncy banjo plinking. Known best for the lyric "you've got women, you've got women on your mind," the song also contains the exceptionally sketchy lines "If her daddy rich/ take her out for a meal/if her daddy's poor just do what you feel." Do not take dating advice from Mungo Jerry.
