There is an important mistake in the published score of Maumbury Rings, not in the notes (as far as I know!) but in the playing order. The instruction al Coda which is printed under measure 28 should be over and at the end of measure 30, so that on the second time around you skip from the high G in m 30 to the high B at m 83.
Here's how its meant to be - sorry if the right margin is clipped.
There is also (only just noticed this!) another slip in the playing order instructions. After bar 82 the instruction DC al (sign) should be different. You are meant to go back to the beginning of bar 1, the first complete bar, not the absolute beginning. You probably worked that one out for yourself but I thought it best to be clear.
