Funnyman Steve Martin is following in the footsteps of stars including Madonna and Jamie Lee Curtis - he's written his own children's book. The veteran comedian, who has no kids of his own, has teamed up with cartoonist Roz Chast on The Alphabet From A To Y With Bonus Letter Z!, which was released in American on Tuesday (23Oct07). The book features illustrations by Chast, accompanied by amusing couplets for each letter of the alphabet - written by Martin. He says, "I'm not sure why I did this. I don't know why an alphabet book popped into my head. "My idea was to write these rhyming couplets with the craziest images I could possibly think up, and then have Roz illustrate them."
