NEW YORK — Only recently given stewardship over his late father's work, Sean Ono Lennon is on a remarkable run.
The only child of John Lennon and Yoko Ono won an Academy Award this year for a short film based on his parents' 1971 song "Happy Christmas (War is Over")" and, a few months later, was nominated for his first-ever Grammy, for producing a box set on the album "Mind Games," originally released in 1973.
