"Your Mother Should Know" is an album track released by the Beatles on their "Magical Mystery Tour" album in the United States and double-EP in the United Kingdom. They released "Magical Mystery Tour" in the United States on 27 November 1967 and on 8 December in the United Kingdom.
Paul McCartney says that he wrote "Your Mother Should Know" specifically as a dance number to be included in the Beatles' "Magical Mystery Tour" film and that it was based on a line from the screenplay for "A Taste of Honey" (1961). "Your Mother Should Know" plays as the Beatles descend a staircase dressed in white tuxedoes. It is a very odd sequence in "Magical Mystery Tour" during which John Lennon almost trips on the steps and Paul is the only Beatle wearing a black carnation (for some unknown reason).
"Your Mother Should Know" is a throwback tune that is so out-of-place for a 1967 rock group that it almost becomes avant-garde. At heart, "Your Mother Should Know" is simply an old British music-hall tune, at least in style, remarkable only because it was written by a modern rock composer. "Your Mother Should Know" is extremely easy to sing and quite catchy, which makes it one of the top Beatles songs for amateur covers on Youtube (it actually would have made a good vocal for Ringo rather than Paul). Basically, "Your Mother Should Know" is an example of self-parody, with Paul openly defying everyone who hates what John Lennon contemptuously referred to as his "granny music." Lennon himself isn't on record as saying anything negative about "Your Mother Should Know" specifically, but only because he wasn't asked. Aside from calling it "Granny music," Lennon also probably would have called "Your Mother Should Know" a throwaway tune, which it unquestionably was.
For many years, Paul McCartney ignored or overlooked "Your Mother Should Know." However, in the 2000s he began digging through some overlooked Beatles album tracks such as "Fixing A Hole," which he also had not performed in concert before the 21st Century but then did. Finally, on 4 May 2013 at the Estádio Mineirão, Belo Horizonte, Brazil, Paul performed "Your Mother Should Know." Paul kept it on the playlist throughout the remainder of his 2013 tour, then dropped it. Paul McCartney apparently hasn't played "Your Mother Should Know" in public since, but then, he has a lot of songs from which to choose.
