In no particular order, I like...
Sam Elliott
Keven Bacon
Audry Hepburn (when I grow up, this is who I want to be
)
Fred Astaire
Bing Crosby
Rob Lowe
Barbara Streisand
Bruce Willis (didn't used to think much of him, but he's been coming out in some pretty good films the past few years. Films that really show his diverse ability)
Martin Sheen
Demi Moore
There are others, the mind has just gone blank for the moment.
I just noticed how many of my actor favorites are musical people as well - I love the musicals, what can I say?
