I'd also like to nominate Steve Seskin for his teaching of all aspects of songwriting.
His personal homepage is at ...
Steve is a fantastic musician, and educator. He's had seven number one hits (including "Grown Men Don't Cry", "Don't Laugh At Me") and is highly respected by his colleagues. In addition, he travels the US with an anti-bullying program for school children and uses music and songwriting as his tools of instruction. He's an incredible, talented man.
Regards,
Noel
