"Summertime Blues" - by Eddie Cochran -- rock and roll will never die!
"Those Lazy, Hazy, Crazy Days of Summer" by Nat King Cole.
"Summer in the City" by the Lovin' Spoonful.
"Hot Fun in the Summertime" by Sly and the Family Stone (one of their best although almost everything they did was great!)
Mungo Jerry: "In the Summertime". You wouldn't get away with the lyrics "a drink and a drive" now! Gotta dig those mutton chops!
