With Midge Ure added to Ultravox, the band continued working more on their unique synthesiser sounds during the recording of their successful "Vienna" album. By that time, he and Ure were close friends, together directing music videos such as Bananarama's "Shy Boy" and "The Telephone Always Rings" by Fun Boy Three. Cross took part in the Band Aid video and wrote the music to "The Bloodied Sword". After another few successful albums – "Rage in Eden" (1981), "Quartet" (1982), "Monument" (1983) and "Lament" (1984) – and the last which was less successful, "U-Vox", and a tour in 1987, the band drifted into other projects and he says, "never got round to working on Ultravox".
