1. The Lovin' Spoonful - 'Summer in the City'
The Lovin' Spoonful's 1966 classic "Summer in the City" began as a poem by frontman John Sebastian's 15-year-old brother, Mark Sebastian. He wrote it in the family's New York apartment and imagined it as a soul song, but when John read the lines "Come on, come on and dance all night/Despite the heat it'll be all right," he knew he wanted it for himself. With a little help from his Wurlitzer pianette and the rest of the Lovin' Spoonful, the song hit Number One in the summer of 1966. It's been used in movies from Die Hard With a Vengeance to The Karate Kid Part III.
