I wonder if that longevity has something to do with another key element of the book — that The Beatles were “a pop group” and “a rock band,” and you talk about them as both.

Sheffield: The fact that they play in both of those leagues is one of the really weird things about them. There’s something utopian about the way they float over that distinction. Their original concept of “rock and roll,” which is what they called it when they were just starting out — it’s amazing how expansive it was. They were really into playing blues, R&B, country, American rockabilly, corny cheesy show tunes, upscale New York professional-songcraft stuff like Goffin and King, girl-group stuff.

It was controversial, even at the time when they were playing in Liverpool. Paul has this funny story in his book about how the other Liverpool bands thought The Beatles were good at playing blues covers, and that it was lame that they wanted to play pop stuff. Mick Jagger was saying, “We were blues purists. We like pop stuff, but we would never do it onstage.” But [Motörhead singer and bassist] Lemmy talked about seeing The Beatles at the Cavern Club, and he was like, “That’s the most ferocious live band I’ve ever seen.” The idea of a 16-year-old Lemmy going to the Cavern for the lunchtime show, and all these office girls who are there with their hair in rollers, dancing around their handbags.

It’s funny that the definitions of rock and pop became more exclusive and narrow-minded since then. The Beatles were beyond that from the beginning. Their conception of rock and roll was so wide-ranging and so imaginative that there was something revolutionary about it. They would try playing anything new: Motown, Carl Perkins, The Music Man, all on the same record or in the same set. They were very self-consciously provocative about that. Even [girl groups like] the Marvelettes or the Shirelles or the Chiffons. [The Beatles] liked singing in that girl-group style of vocals together. Like, no, The Rolling Stones did not do that.

It’s my great pleasure to make my MTV News debut by interviewing Rob Sheffield about his tremendous new book Dreaming the Beatles, the best thing about the band I’ve ever read. It sidesteps the canonicity argument completely and talks about how the Beatles’ presence in pop culture didn’t just end with their amazing eight-year run, but continued to grow and change and get even bigger among different groups of kids and musicians every decade since. Absolutely stellar work, and I’m so glad I got to pick Rob’s brain about it.

I was one of the voters drawn from across the television landscape — actors, directors, writers, producers, critics — and polled to put together Rolling Stone’s list of the 100 Greatest TV Shows of All Time. My man Rob Sheffield did a bang-up job with the write-ups.
