“The list of heavy-drinking composers is worthy of Monty Python’s ‘Philosophers’ Song’. It includes Handel, Mozart, Beethoven, Schubert, Schumann, Liszt, Brahms, Mussorgsky, Tchaikovsky and Sibelius. There are no reports of Bach getting drunk — but during a fortnight’s trip to Halle in 1713 his beer bill came to 18 grossen, which suggests that he got through eight gallons of the stuff (plus lashings of brandy). Berlioz and Wagner preferred opium, and it’s not fanciful to suggest that you can hear it in the Symphonie Fantastiqueand Tristan. Can you hear alcohol in the music of the boozers?”
