With the release of their fourth album, "Below the Salt", later in 1972, the revised line-up had settled on a distinctive electrified rock sound, although they continued to play mostly arrangements of very traditional material, including songs dating back a hundred years or more. Even on the more commercial "Parcel of Rogues" (1973), the band had no permanent drummer but, in 1973, rock drummer Nigel Pegrum, who had previously recorded with Gnidrolog, The Small Faces and Uriah Heep, joined them, to harden up their sound (as well as occasionally playing flute and oboe).
