“What's the New Mary Jane” is a nursery rhyme-like song, one of John Lennon’s most peculiar offerings. It was recorded for late 1968’s double album The Beatles (i.e. the White Album) but, literally, did not make the cut. Nonetheless, John Lennon would not let it go.

Andrew Sarris, doyen of auteurist film critics, dubbed A Hard Day’s Night “the Citizen Kane of jukebox musicals”. Wild over-praise, or sly, back-handed compliment?

Do we need any more Beatles books? The answer is: that’s the wrong question. What we need is more Beatles books that are worth reading. As the musician and music historian Bob Stanley pointed out, in his 2007 review of Jonathan Gould’s Can’t Buy Me Love, probably the best biography of The Beatles to date, “the subject is pretty much inexhaustible if the writer is good enough.”

The blurb on the front of the double-CD set The Hamburg Repertoire says it collects “The original recordings of songs performed by The Beatles on stage in Hamburg.” Disc One opens with Little Richard’s “Long Tall Sally.” Disc Two ends with Chet Atkins’ version of the “Theme From ‘The Third Man’.”

When first I clicked on the stream for this album, I really wasn’t sure about it. In fact, I thought I wasn’t going to like it, much as I had wanted to. But I’ve had it playing almost continuously while I’ve been dealing with mindless stuff – and I’ve come to like it.

Not without reservations of course – there are always reservations – but it’s got under my skin and I’m now properly in the groove, appreciating what Lucinda Williams is doing, delving into this most hallowed of song catalogues and bravely tackling numbers that are rarely, if ever, covered. As is her way.

“We hope if you like it, you'll buy it,” says Paul McCartney. It’s 4 April 1963 and The Beatles are on stage and about to perform their third single “From Me to You.” It’s out in a week.

To his left, John Lennon instantly responds to the entreaty. “And if you don't like it,” he retorts. “Don't buy it.”

Lisa Cortés’s fast-paced documentary Little Richard: I Am Everything opens with a TV interview made in 1971, 16 years after the rock 'n' roll pioneer became an overnight success with groundbreaking hits like "Tutti Frutti" and "Good Golly Miss Molly".

A strange new single went on sale in Britain’s record shops in April 1962. Credited to Ray Cathode, “Time Beat” combined a metronomic rhythm with peculiar, otherworldly sounds. It was not a standard pop record. The flipside, “Waltz In Orbit”, was also about its tempo and was just as weird. Not many copies were sold.

The Beatles loomed over everything else. It wasn’t inevitable, but the arrival of the revealing Revolver box set and Peter Jackson’s compelling Get Back film confirmed that there is more to say about what’s known, and also that there are new things to say about popular music’s most inspirational phenomenon of the 20th century.
