Actually, Cat Stevens did a few concerts in the past year. In November of 2003 he did the Nelson Mandela Aids Benefit Concert and in December another performance, and if I remember right he performed Wild World and Peace Train. And I believe he's releasing a CD of songs for children this month.
In 2001, his boxed set was released, and he donated the royalties to The September 11th Fund, and his charity, Small Kindness.
