So...I went back this morning and listened to the song again.
As you likely deciphered...it's been a long, LONG time since I last did that. You know what? Except for the "no man can cling" bit...It's not THAT bad. Not nearly as bad as I remembered it. The "I try to run far 'way/I tried to rationalize" bits are a little 'strange'...but maybe I've been a little bit too harsh. Maybe I was a worse critic back in '65...when I was only 13.
So ya...Most of it, in fact, is kind of decent...or, at the very least better than I remembered it. The backing track and that sax bit Brian sneaks in under the vocal about 46 seconds in always worked.
Now I'm going to have to upgrade my rating of the album.
