Elvis is the only one mentioned so far that I think was attractive, but ideally pre-side burns.
I guess it doesn't help that I really can't be doing with all that late 60's and 70's hairiness. All those beards and massive hairdos - bleurgh!
I agree with a previous poster - I definitely tend to prefer actors' looks over musicians'. Not keen on the sweaty, dishevelled rock god look at all
