 Of the "Choral Symphony" completed in 1924, Matthews writes that, after several movements of real quality, the finale is a rambling anticlimax.Holst's penultimate opera, "At the Boar's Head" (1924), is based on tavern scenes from Shakespeare's "Henry IV, Parts 1" and "2".The music, which is largely derived from old English melodies gleaned from Cecil Sharp and other collections, has pace and verve; the contemporary critic Harvey Grace discounted the lack of originality, a facet which he said "can be shown no less convincingly by a composer's handling of material than by its invention".
