My bad

The slogan "a little dab'll do ya" is definitely Brylcreem. Here are the full lyrics:

Bryl-creem, a little dab'll do ya, Use more, only if you dare, But watch out, The gals will all pursue ya,-- They'll love to put their fingers through your hair.

I got them from Wikipedia, where I also learned that this slogan was the basis for the famous Flintstone "Yabba-dabba-doo"

You can even watch an earlier version on You Tube.




Good times.
