I enjoy listening to the singers on American Idol. I was struck by David Archuleta's rendition of "Imagine". It troubled me at first, since most versions sound like either that of a poor Lennon imitator, or of a Vegas lounge singer (in the Bill Murray vein.) But listening to the song again, I liked David's version quite it bit. It wasn't perfect, but I think Lennon would have liked this. It had one thing John ached for but could not conjure up, not at the point in life when he'd written it: innocence.
