The Byrds' 'So You Want To be a Rock & Roll Star' was an attack on the Monkees pre-fabricated pop. Whcih is ironic, considering the Byrds debut album probably featured the same LA session musicians as used by the Monkees on their albums.
The Monkees have yet to reply.
Didn't Elvis Costello once write a song ( possibly called Veronica ) where he slagged off both John Lennon's "Imagine" and Pink Floyd's "Another Brick in the Wall" ?
Well, if you're going to write a slag-off song, thats just the type of maudlin s**t to point your canons at. I must dig up that song.
