Dr. Feelgood are a British pub rock band formed in 1971. The band's name derives from a slang term for heroin or for a doctor who is willing to
overprescribe drugs. It is also a reference to a 1962 record by the American blues pianist and singer Willie Perryman (also known as "Piano
Red") called "Dr Feel-Good", which Perryman recorded under the name of Dr. Feelgood & The Interns.
