The Beefheart/ Magic Band identity crisis continued on this, his last single release. Sleeve says "Captain Beefheart & The Magic Band" and the label says "Captain Beefheart And His Magic Band".
If the image in the centre of the sleeve is embossed then it is a 9 December 1980 issue (ie. first 12" issue). The 1981 re-issue had flat sleeves with no embossed images. I also think the font on the labels looks slightly bolder on the 1981 re-issue.
