Francis Bacon [1909-1992] "would get up in the morning at 7am, paint until noon.
Have a smart lunch in Saint James's, go to his gallery
Marlborough, get some money from the drawer, go drinking in the afternoon until the early evening and then be taken home in a taxi by somebody then wake up at 7am then paint clear headed until noon again."
