columns of TV criticism in the 70s takes practice, and if it's not your main occupation, you won't achieve it.
I think it's fair to say John Peel was not a natural writer. Margrave Of The Marshes is good - or, at least, the first half is, which is the bit Peel wrote - but it's clear that he developed slowly as a writer. Some of the later pieces here are fine, and there are amusing one-liners from all periods; he nails my opinion of Springsteen, in 1975, by observing that he "[...] offers us an enjoyable supper-club pastiche of rock's brief history, served up in West Side Story-styled tat". However, too many of the articles are rambling and inconclusive. Still, an easy read and enjoyable in parts.
