"Gloria" was the second single released from U2's album, October. The track has remained a staple in U2's live set ever since its release in 1981. Celebrating its 40th-anniversary, this 12" single is pressed on transparent yellow 180-gram vinyl and is housed in a high gloss gatefold jacket with a poster included. It features the studio version, plus three live recordings of the track from different decades: Dublin in 1990, Boston in 2005, and London in 2015.
