"In the Summertime" - Mungo Jerry

Mungo Jerry's debut single, "In the Summertime", is available on iTunes. Ray Dorset, the band's lead singer, wrote and composed the song, which celebrates the carefree days of summer. In 1970, it topped charts all over the world, including seven weeks on the UK Singles Chart, two weeks on one of the Canadian charts, and three weeks on the Billboard Hot 100 singles chart in the United States. It went on to become one of the best-selling singles of all time, selling 30 million copies.

Dorset has stated that the song took him only ten minutes to write, and he did use a second-hand Fender Stratocaster while on leave from his regular job, working in a Timex lab. Dorset sued his former management company, Associated Music International, which was run by his former friend and business manager Eliot Cohen, in 2012, claiming over £2 million in royalties from the song that he believed were withheld from him.
