An example:

Now I spend my time, following him whenever he’s with you
or
I know (I know) that you’re sleeping with another guy

How about some Faire tunes?

“The Sailor’s Prayer” sung by a bartender
“Mary Ellen Carter” by Gordon Lightfoot (just for contrast)

(Sublight, a couple of buddies and I spent much of a 12-hour trip doing Chistopher Walken and Sean Connery impressions last week. I even sang the first of the songs above in my Connery voice.
