Variant labels added. Although the sleeve still references Mickey Mouse Club on my copy, the blue label omits that reference. Also in the process of scanning I noticed the incorrect credit on the sleeve (or is it incorrect label credit?) and had something added to the Notes about that.
Incidentally, these singles appear to be the only place where Haley's band is credited as "4 Aces of Western Swing." The band was more widely known as the Western Aces.
Interestingly according to 45cat this was released on 45 in September.. I didn't think the separated out the dates like that. Is November or September confirmed for release? This was the first single to be released under the Comets name but it took another year or so for them to start using "Bill Haley and the Comets" (or "His Comets") on the labels.
