This is one of two original tracks from Paul McCartney's 2012 "pop standards" album, Kisses On The Bottom, the former Beatle's tribute to classic songwriters of the 20th century. Said Macca: "When I kind of got into songwriting, I realized how well structured these songs were and I think I took a lot of my lessons from them. I always thought artists like Fred Astaire were very cool. Writers like Harold Arlen, Cole Porter, all of those guys – I just thought the songs were magical. As I got to be a songwriter I thought it's beautiful, the way they made those songs."
The album marks the first time McCartney recorded without playing guitar, bass or piano. Instead he was backed by Jazz singer Diana Krall's band. "It was very spontaneous, kind of organic, which then reminded me of the way we'd work with the Beatles," explained McCartney. "We'd bring a song in, kick it around, and by the time everyone kind of had an idea of what they were doing, we did the take live in the studio."
This ballad features some guitar work from Eric Clapton. Probably the best known track that features the talents of both McCartney and Clapton is the Beatles' classic "While My Guitar Gently Weeps
The "Kisses On The Bottom" title is taken from a lyric on the album's opening track, a cover of Fats Waller's 1935 hit "I'm Gonna Sit Right Down And Write Myself A Letter." The lyric is: "I'm gonna sit right down and write myself a letter and make believe it came from you/I'm gonna write words oh so sweet/A lot of kisses on the bottom/I'll be glad I got 'em."
McCartney admitted to London's Sunday Times that his love of "mischief" led him to pick the controversial title. "I like mischief," he said. "It's good for the soul, it's always a good idea — if only because people think it's a bad idea."McCartney added that his record label was concerned when they learnt of his intentions for the title of the disc. "I made the suggestion and got this nervous text from the label which said, 'Paul, under no circumstances can we do this,'" he said. "One of the guys said he felt like he'd been punched in the gut."
Paul penned this song whilst sheltering from the rain during a holiday in Morocco with his wife Nancy Shevell. He revealed to Mojo magazine: "It was inspired by the hotel pianist, an Irish guy who liked to drink. He would rattle through this repertoire of old songs from my dad's era and before. It was inspiring - his command of them, and his love for them! I had a moment one afternoon when the hotel was quiet and I just got on the piano. The spirit of what he was doing led me down the path."
McCartney directed the song's black and white music video, which features Hollywood stars Natalie Portman and Johnny Depp each interpreting the lyrics of the song using their own form of sign language. Depp plays guitar in his version and recorded the track's guitar solo live, which was performed on the record by Eric Clapton. McCartney worked with cinematographer Wally Pfister (Inception, The Dark Knight), editor Paul Martinez and producer Susanne Preissler to create the clip, which was based on an original idea by Stella McCartney. Asked why he picked Portman and Depp to star in the video, Sir Paul said: "Well, they're just nice people, some friends from way back and they were just very kind to do it. I was very pleased to work with them."
Deaf music fans noted that both actors made unfortunate slip-ups with their translations. Depp embarrassingly makes the gesture for the word "enemy" while attempting "valentine" and both he and Portman make the motion for the word "tampon" instead of the word "appear."
Kisses On The Bottom won the 2013 Grammy for Best Traditional Pop Vocal Album. It was Sir Paul's 17th Grammy award and his first for a record containing new material since his Beatles days.
