That's very interesting, SINSULL. Maybe the Burl Ives/sexiness thing has to do with context. My early memories of him are as the voice of the snowman in one of those claymation Christmas specials from the 1960s, which puts him (permanently, I'm afraid) in the category of 'too wholesome to be sexy'.
I will 'fess up on a little secret, though. The only time I ever felt the hots for a musician was when I saw a guy playing a long necked Seeger banjo. That long neck really showed the muscles of his arm off to good advantage, and the way he held it made me want to know what it felt like to be that banjo. So I guess I'll have to put myself in the banjos being sexy (sometimes) camp.
Guitars have an effect on me too, but it's more of a pulling at my heartstrings kind of thing rather than lust.
This thread is almost 200 posts long. Should there be a part two?
