Truly one of the all-time great bluegrass singers, the self-proclaimed "King of Bluegrass" was Bill Monroes' lead singer in the Bluegrass Boys in the early 50's. He also played with the Osborne brothers for many years, and of course with his own band, the Sunny Mountain Boys, with J.D. Crowe. His voice can be heard on such Bill Monroe classics as "Uncle Pen", "0n and On", and "Letter From My Darlin", and he is best known for his classics, including "Hit Parade of Love", "Sunny SIde of the Mountain" and "Sophronie". A bluegrass "character" in every sense, Jimmy unfortunately didn't gain the widespread public recognition of Monroe, Flatt and Scruggs, or the Stanleys, but he has a special place in the hearts of all true traditonal bluegrass enthusiasts.
