Mungo Jerry is an English folk/classic rock group from Ashford, Englandwhose greatest success was in the early 1970s, though they have continued throughout the years with an ever-changing line-up, always fronted by Ray Dorset. They are remembered above all for their hit "In the Summertime". It remains their most successful and most instantly recognisable song. Their name was inspired by the poem Mungojerrie and Rumpelteazer, from T. S. Eliot's Old Possum's Book of Practical Cats.
