In the Summertime Mungo Jerry (Dawn, 1970)
In the Summertime was the debut single of British rock band Mungo Jerry. Lead singer Ray Dorset wanted to celebrate how carefree summer days are. It reached #1 in 19 countries. (In fact, the only country’s chart it didn’t hit #1 was in Poland where it only hit #2.) In the Summertime is considered one of the best selling singles of all time, selling over 6 million copies. It only took Dorset 10 minutes to compose! In the Summertime is the only Mungo Jerry hit outside the UK.
