Lord Hereford’s Knob is, quietly, one of the best songs on CSI:Ambleside. Of course, every HMHB album needs a track celebrating English (and indeed here, Welsh) geography, and this one is one of my favourites ever. Plus it namechecks some old HMHB songs! In case you didn’t know, Lord Hereford’s Knob – AKA Twmpa – is a peak in the Brecon Beacons. Thanks Giles
