Sorry, Bert, I never heard of these. All I can do for you is to give you what I consider to be the most probable correct version (one bold guess involved). Your translation is fine except that "harre" is "wait".

Sei nicht böse
Sei wieder gut
Sei nicht böse
Mach kein gesicht

Mit meiner Gitarre
Steh ich hier und harre
Harre nur alleine
Ach Liebchen bleib bei mir

The German equivalent to Mudcat, Frank Petersohns http://ingeb.org/, has no question and answer section, but Frank knows a lot of songs and is a nice chap to mail with. He might put these two verses into his "wanted/Schnitzeljagd" section.
