Simmons lived in Israel until he turned eight and was raised by his mother who survived a Nazi concentration camp. And like many immigrants to the US, he is a passionate believer in the American dream. His credo - 'rock'n'roll is about finding out who you are' - strikes a deeply personal chord.
'What I fell in love with about Christ's Hospital was that not everybody's rich - what counts is having the
brains and the ambition.' And, six months after filming Rock School, Simmons is still trading e-mails with Emperor Josh Bell.
Don't be surprised if Simmons, ever the entrepreneur, ends up managing him.
Rock School starts on Channel 4 on Friday at 9.30pm.
