CK 6--From under her velvet gown she drew a gun and shot him down.
Miss Otis Regrets has the line "And from under her velvet gown she drew a gun and shot her lover down". Is that the song you're thinking of?

Given the hint, CK 9--I was blinded by the glare of your headlights.. must then be YOU'RE A DETOUR ON THE HIGHWAY TO HEAVEN.

Best wishes,

Bente
