"Get Over You". Much of the material upon their first album had been performed regularly at the Casbah, and the band were able to record this album in the space of less than four weeks. Following the release of "Get Over You" in February 1979, the Undertones' eponymous debut album was released in May. The primary lyrical concern of the songs focused upon youthful relationships and adolescence. Three further punk singles "Jimmy Jimmy", "Here Comes the Summer" and "You've Got My Number (Why Don't You Use It?)" were released between April and October 1979, each to critical acclaim.
