Here is one that I don't think anyone has mentioned, and I cannot believe that I forgot it:
AC/DC- Starlight Express (along with Dangerous Game, the sexiest song I know)
Forgot about The Tennis Song and As Long As You're Mine....
(btw- I'm just leaving Cabaret, Chicago, and The Rocky Horror Show out of my list because for all of these the whole bloody show is sexy -to me).
Also, maybe I'm weird but....
Waltz for Eva and Che- Evita (depending on the staging, I saw a production where they waltzed thisclose for the entire song, but never actually touched...terribly hot)
Kiss of the Spider Woman (most of the songs, actually, but particularly the title song)
Rhythm of Life- Sweet Charity
Alive- Jekyll & Hyde (with Robert Cuccioli singing it)
Turn Back, O man- Godspell (dependign on how it is done, seen it both incredibly sexy and incredibly pathetic)
You Are Woman, I am Man- Funny Girl (funny and sexy at the same time, unbeatable combination)
(yup, I'm definitely weird)
Carpe Noctem...
