U2

U2 are a world-famous Irish rock band of the 1980s to the present. As U2 emerged as the 'biggest band in the world' in around 1987 after the release of their album 'The Joshua Tree', it is ironic that in the last Doctor Who story of the original run in 1989, Survival, Ace picks up the U2 record 'War' in Midge's flat, and comments disapprovingly: "Are they still around, they were well old when I left!" This, to date, is the only reference to U2 in any Doctor Who story, in the old series or new.
