The Beatles didn’t singlehandedly convince ‘the establishment’ that rock and roll was worthy of the same respect as ‘proper’ music, but they certainly contributed more than a fair shakes towards earning that respect. It’s generally agreed that Sgt. Pepper was a catalyst in establishing rock music as a real art form, and She’s Leaving Home is generally pointed out as proof that rock musicians are capable of producing works of great sensitivity and nuance. The youths of the time needed no convincing on this point, but the squares were reluctant to give those long-haired upstarts their due as songwriters and composers. All they needed was Paul McCartney in his most dewy-eyed mode, thoughtfully acknowledging the sad and inevitable gap between between generations and their inability to relate to one another, backed with a plush string arrangement. Now, of course, the artistic validity of rock as a genre is beyond any shadow of a doubt; if anything, it has become overly entrenched as the dominant cultural standard. It strikes us as outlandish and unthinkable that anyone would have ever questioned it.
