He's alright. Back in the 60's he was the first of his kind. So I can understand why he used to be so popular.
Other than a few songs....well, have you heard the Star Spangled Banner by him......jumpin jesus on a pogo stick is it god awful.
it was supposed to be 'god awful'. It's is one of the most important political songs of the age. It's a musician's way of burning the flag in protest.
It's a protest against the USA invasion of Vietnam and the unnecessary deaths of 50,000 young American men.
you can listen to just how 'god awful' it is here
