1) Boy, is this vocal strident! It takes your head off at 1 to 2kHz. Obviously it works against the track but I wouldn't call this a model vocal sound by any stretch of the imagination.
2) Boy, is there a lot of reverb on this vocal. And it has a pretty long tail as well. Popular music has gone through cycles of lots of reverb during a mix to almost none at all. This was at the top of a "lots of reverb" cycle.
3) There are plenty of punches on this track. Some are pretty noticeable and some not so much. You don't hear any of them against the track, which is the way it's supposed to be.
4) There's a lot of guitars that pop up during the song. I assume that's because some of the empty space on the vocal tracks were used to share with the guitar when they needed another overdub. Don't forget, this was in the days of magnetic tape and limited tracks.
