 This was confirmed by Jeff Lynne on 3 October 2012 on "The One Show".AllMusic's Donald A. Guarisco considered "Mr. Blue Sky" a "miniature pop symphony" and a "multi-layered pop treat that was a pure Beatles pastiche", saying that "the music divides its time between verses that repeat the same two notes to hypnotic effect a la 'I Am The Walrus' and an effervescent, constantly-ascending chorus that recalls".Guarisco also pointed other references to the Beatles such as "the staccato bassline recalls the chorus of 'Hello Goodbye' and pounding piano lines and panting background vocals recall the midsection of 'A Day In The Life.
