Shortly before his death in 1980, Lennon commented that "Although the lyrics don't resolve into any sense, they're good lines. They certainly work ... but if you read the whole song, it doesn't say anything" and added the song was "beautiful – and I never wished I'd written it". Lennon made reference to "Yesterday" in his song "How Do You Sleep?" on his 1971 album "Imagine". The song appears to attack McCartney with the line "The only thing you done was yesterday, but since you've gone you're just another day", a reference to McCartney's recent hit "Another Day". At the 2006 Grammy Awards, McCartney performed "Yesterday" live as a mash-up with Linkin Park and Jay Z's "Numb/Encore".
