ST-0097 etched in run-out.
This 45 also exist as a stock copy with a flipside called "Really Rockin'".
This group also released an ultra rare 45 on Shrine Records (#106) (http://www.discogs.com/label/Shrine+Records) called "Mad At The World"/"I'm So Devoted". There are also 45's on the Hem and Triple G labels by The Epsilons, but I'm not certain that's the same group. Probably though.
