Song in this movie trailer

This song has been bugging me for a few days now.

Lyrics sound like Break It Up Break It up... but its not from foreigner or jorn lande. Sounds like its from the 60's / 70's but i could be wrong.

I found a website that claims one of the songs from the "Dinner for Smucks" is called "Heartbreaker" by The Milk.

Try the following websites for more information.
