Dr. Feelgood are a British pub rock band formed in 1971. The band's name derives from a slang term for ****** or for a doctor who is willing to overprescribe *****. 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. The song was covered by several British beat groups in the 1960s, including Johnny Kidd & The Pirates.
