In a famous, oft-repeated British TV comedy sketch, first broadcast on 25 December 1971, the classic duo of Eric Morecambe and Ernie Wise wreak havoc in a performance of the opening of Edvard Grieg's Piano Concerto in A minor, conducted by André Previn. Pianist Morecambe and his ‘manager’ Wise make a string of ridiculous demands: they want to perform what Morecambe calls a ‘special arrangement’ of the concerto with the orchestra playing the opening flourishes and the piano the main theme (Previn reluctantly agrees); they deem the new orchestral introduction ‘too short’ and suggest contacting Grieg to get him to lengthen it; and, after missing Previn's cue on account of a poor sight-line to the conductor, ask him either to wear high heels or to ‘jump up in the air’ in order to be visible. Finally entering at the appropriate moment at the third attempt, Morecambe delivers a grotesquely butchered version of the main theme. Reprimanded by Previn for ‘playing all the wrong notes’, Morecambe purses his lips, grabs his conductor by the lapels and, with the exquisite timing that made him one of Britain's greatest post-war comedians, delivered his coup de grace: ‘I'm playing all the right notes, but not necessarily in the right order’.
