5. Mungo Jerry - 'In the Summertime'
What's that? You've never heard of Mungo Jerry and you don't know "In the Summertime?" Sure you do. You just don't realize it. Listen to the first five seconds of the song and it'll pop right into your head. "Oh yeah," you'll think. "That thing." The supremely catchy song was released in 1970 by the British pop band Mungo Jerry. It's their only big hit, but it was a doozy. It sold millions of copies and flew up the charts all over the world. The group still tours and is still fronted by "In the Summertime" singer and writer Ray Dorset. Check them out at the Hard Rock Café in Bucharest, Romania or at "Private Party" in Ringwood, England. Chances are good they'll play "In the Summertime."
