After Moore's departure, Thin Lizzy continued the tour for a few nights as a trio before Lynott brought in Midge Ure to replace him on a temporary basis. Ure had prior plans to join Ultravox, but had co-written a song, "Get Out of Here", with Lynott on "Black Rose: A Rock Legend", and agreed to help Thin Lizzy complete their touring commitments. He also contributed guitar parts for "The Continuing Saga of the Ageing Orphans", a compilation album of remixed and overdubbed versions of Eric Bell-era tracks. On their return to the UK, the band were to headline the Reading Festival for the second time on 25 August 1979, but had to cancel due to the disruption within the line-up.
