Dr. Hook (& The Medicine Show) were formed in Union City, New Jersey, USA in 1968. The original lineup consisted of Ray Sawyer, Dennis Locorierre, Bill Francis, John David and George Cummings - although there were countless lineup changes over the years.
Two years after Sawyer left in 1983 the band split up. Since then Sawyer has begun touring as "Dr Hook featuring Ray Sawyer" and Locorierre has also promoted himself as "The voice of Dr Hook".
Trivia: In a live webcast performance from Atlanta Bon Jovi performed "Sylvia's Mother" by Dr Hook - declaring the song "One we should have written".
