I have been to that lovely little mosaic that they have build across the street from where John Lennon was shot... it is nice. For some reason though, I don't feel like it catches the magic... or even that the word magic catches the just want John Lennon did for music.
I told someone once that if John Lennon were a live today and making music it would sound a lot like Modest Mouse did on Good News For People Who Love Bad news... (that was a great album) but i since then i think i have realized that if John Lennon were a live today and making music, it would sound much like the music that is around today... because in his time he made music like today's music.
That was a ramble, this is a video of John Lennon doing Instant Karma:
This is a lovely video:
