However, on 4 July 1979, after playing their Day on the Green set in Oakland, Gary Moore abruptly left Thin Lizzy in the middle of another tour. Years later, Moore said he had no regrets about walking out, "but maybe it was wrong the way I did it. I could've done it differently, I suppose. But I just had to leave." He subsequently pursued his solo career, releasing several successful albums. He had collaborated with Lynott and Downey on his 1978 album "Back on the Streets" and the hit single "Parisienne Walkways" before leaving Thin Lizzy, and in 1985 he and Lynott teamed up again on the UK No. 5 single "Out in the Fields". Gary Moore died of a heart attack in Estepona, Spain on 6 February 2011, aged 58.
