John Lennon's ‘70s solo albums found him exorcising his own evil spirits. He's scathing and sore in the itchy rockers “I Found Out” and “Well Well Well,” and screaming with desperation in the funky “What You Got.” The fragile power ballad “How?” and the deep soul of “Hold On” show how shaken and vulnerable he could be, while “Aisumasen (I'm Sorry)” recasts his own God as a direct apology to Yoko Ono.
