Gallagher worked with the Clash's drummer Topper Headon again in a short-lived band called Samurai, and again when they recorded Headon's "Waking Up" (1986), appearing with Bobby Tench and Jimmy Helms. Samurai guitarist Henry Padovani briefly described Gallagher in his memoir: "He had a family, was the serious one of the group, never snorted any coke and managed to somehow control Topper a little. Playing with this talented musician was a pleasure." Gallagher has also performed and recorded with Paul McCartney, Roger Daltrey, Robbie Williams, Dave Stewart and Annie Lennox. More recently he returned to perform with The Blockheads and John Steel's The Animals and Friends.
