reveals what a supreme vocalist he is." Guarisco described his singing as "a wild-eyed wail of a vocal that is a perfect blend of soulful grit and rock energy." Vincent Benitez particularly praised the vocal performance in the outro, stating that "McCartney shines as a bluesy vocal soloist, ad-libbing as the music fades out." In the book The Rough Guide to the Beatles, Chris Ingham noted a similarity between McCartney's vocal in "Call Me Back Again" and that in The Beatles' song "Oh! Darling," although he considered "Call Me Back Again" to be "an inert sludge rocker." Author Tim Riley also remarked on the similarity between "Call Me Back Again" and "Oh! Darling." Robert Rodriguez, calling the song "a piano-based soul shouter" took the "Oh! Darling" analogy further, stating that it "fully achieved what the Fabs' 'Oh! Darling' only hinted at, with a full-throated vocal unheard since the coda of 'Hey, Jude' seven years before." McCartney himself stated "I ended up just sort of ad-libbing a bit, stretching out a bit. I like that myself. I had a chance to sing."
