According to the album's press release, Paul McCartney suggested John Pizzarelli perform tracks from his canon, and offered the title.[2][3] Pizzarelli had previously performed Beatles songs in his 1996 album Meets the Beatles.[4]
Writing for AllMusic, Stephen Thomas Erlewine praised the source material, but commented the "key to the record's success is Pizzarelli himself, who delivers upon the laid-back promise of the title but is savvier than he needed to be, which is why Midnight McCartney satisfies."[1]
Christopher Loudon wrote for the JazzTimes that "the set’s not all midnight lace. Indeed, lovely as everything wrapped in Pizzarelli’s trademark silken lilt is, the more adventurous selections are more interesting."[2]
The Times music critic Chris Pearson described the album as "delightful."[3]
In an interview with Pizzarelli, James Wood from Guitar World commented the tracks were "all tastefully done in Pizzarelli’s trademark style."[6]
