It's not the complete answer, but Matt Hurwitz's Studio Daily article on the recent restoration of “A Hard Day's Night” for the recent Criterion Collection release published Aug. 11 does have some first-time specifics on who's behind the “Train Music” song in the film. And one of the players may well be session player James Page, aka guitarist Jimmy Page.
Giles Martin, son of Sir George Martin, has been saying it wasn't his belief that the group was the Beatles.“My instinct says it’s not The Beatles, but more likely the session players my dad would have gotten in for the soundtrack recording,” the article quotes him. Prolific studio guitarist Vic Flick, who was suspected of being on it, tells Hurwitz he also isn't.
But drummer Clem Cattini, once of the Tornadoes, says he is, and likely so is bass player Alan Weighell. But even more significant is that Cattini says Page may also be, though Hurwitz said in a phone interview Page himself has not confirmed it but is being contacted about the track. Both Cattini and Weighell had regular jobs as session players for Martin.
"It was interesting how these musicians could quickly identify each other's playing, and quite easily," Hurwitz tells Beatles Examiner. "Vic Flick could tell immediately that, though he plays on 'This Boy' on the soundtrack album, he was not on the 'train music' cue. And bass player Herbie Flowers, who later went on to record for George, upon hearing the cue, said, 'That's Clem. And that sounds like Big Jim Sullivan and Jimmy Page playing the guitars,' which Cattini also said. They worked with each other for so many years, on so many sessions, they can hear not only their own playing, but that of their colleagues."
Hurwitz's article also details the intricacies of the AHDN restoration, Criterion's first 4K reconstruction. “We’ve always scanned in 4K, but we’d been working at the 2K level prior to this project,” said Lee Kline, technical director at Criterion.
