As part of a welcome recent trend, the Today programme this morning was presented by Monty and Mish, the twin set who occasionally manage to drop pearls. Devoid of the deadweight of burnt-out testosterone that burdens the older male presenters, Monty and Mish manage at times almost to sing, but since ’tis the season for mistletoe in the house and so guest editors on Today, the links were peppered with references to “the musician P J Harvey” and “P J Harvey the musician”, who, it was said somewhat defensively, was responsible as guest editor for doing ‘something unusual’ to the programme. As doing anything let alone something unusual to the Today programme is known to provoke a mailbag the size of a mammoth, Monty and Mish were right to sound anxious, but the bigger question was could anyone really do anything unusual to the Today programme? The answer, as it turned out, was an unexpected yes.
