At this time, Ure also co-wrote and helped produce the 1984 Band Aid single "Do They Know It's Christmas?". The group also appeared at Live Aid the following year and played four of their hit singles ("Reap the Wild Wind", "Dancing with Tears in My Eyes", "One Small Day" and "Vienna"). With Ultravox being swiched in the running order so that Princess Diana could see The Boomtown Rats before leaving Wembley, the start of the Ultravox set was lost to a poor hand-over from an over-running foreign link up. As the concert was never officially archieved, this could not be restorted to the partial record of the event available on the official DVD.
