John Lennon wrote many songs targeted at people in his life but he said one track was definitely not about Paul McCartneyAfter The Beatles disbanded, John Lennon and Paul McCartney were entangled in a public feud for a brief time. The feud manifested in a few of their solo songs, with the two former bandmates exchanging blows in lyrics the best way they knew how. Many theorized that one John Lennon song was about Paul McCartney, but Lennon clarified that it was “for sure,” not about Sir Macca. “Steel and Glass” is a song from Lennon’s fifth solo album 1974’s Walls and Bridges. It’s one of Lennon’s more vicious songs, like “You leave your smell like an alley cat.” This led many to speculate about who the song might be about, and one person who was a possible target was Paul McCartney.
