After The Beatles, he put out some pretty awful music like that "Imagine" song and the one song where he screams "Mother" at the top of his lungs. Horrible stuff. He did have a couple of catchy songs on that last album of his ("Double Fantasy") but then he got shot.
I’m smiling because you are *explaining* that Lennon was a rock star who played in a band by the name of the Beatles in the 1960s. I think I’m finally getting old. :-D
