For a start this movie was at least an attempt to follow the American lead and to call Tony Crombie a feeble attempt to copy Haley is just not on-he was an already well established jazz musician who was never afflicted with the same snobbery as many of his ilk. These kind of films were no more than something to hang the songs to same as most of the Elvis movies. True the stories were absurd but when it comes to silly musicals it began with the Busby Berkeley ones in the 20s. Crombie and Baxter made credible versions of mainly U S songs and if you go further you find the former in the 60s with organist Alan Haven recording Lennon & McCartney The first real rock'n'roll movie was A Hard Days Night,preceded by Its Trad Dad from the same director and which saw jazz and pop intermingled. I've seen worse than this-try Gonks Go Beat
