Another Day does not appear on any U2 album. During the February 26, 1980 concert at the National Stadium in Dublin, Bono introduced the song indicating it was their new single on the CBS label and that they would not be on the CBS label much longer. Later that evening U2 were offered a deal by talent scout Bill Stewart of Island Records. This single was released only in Ireland and only in the 7" format. Initial pressings featured the CBS 'sunburst' label and a promo postcard with a black and white photograph of the band on the front and artwork by Bono on the back. An early demo version of Twilight was on the b-side.
Bono provided the artwork and handwritten notes/credits for the sleeve, which included thank you's to Elsie and the [Lypton] Village. Bono's original sleeve artwork was 'cleaned-up' by designer Steve Averill. The face within the balloon image was based on Conrad Vedit's face in the film The Cabinet of Dr.Caligari. In 1982, Another Day, along with the Three EP, 11 O'clock Tick Tock and I Will Follow were re-issued as a 4 x 7" set entitled '4 U2 Play' in Ireland. Although Another Day was originally released on black vinyl, these re-issues came on yellow, orange, and white vinyl.
