In 1937, John Barbirolli took six pieces by Henry Purcell and arranged them for an orchestra of strings, horns and woodwinds. Nothing unusual about that: arranging baroque music for modern symphony orchestras was what famous conductors used to do. Beecham and Hamilton Harty re-upholstered Handel. Mahler did something similar with Bach, then directed the result from a grand piano, and wouldn’t you give anything to have heard him? All good clean fun in those innocent days before the advent of historically informed performance.
