Having returned to the U.K, Shirley re-formed Humble Pie in 2001 with a line-up including the original bassist Greg Ridley, former Humble Pie member vocalist and guitarist Bobby Tench and new rhythm guitarist Dave Colwell (of Bad Company). They recorded Humble Pie's thirteenth studio album, "Back on Track" (2002), which comprised new songs and was released by Sanctuary Records. Keyboard players Zoot Money and Victor Martin were brought in for recording sessions. A brief tour of UK and Germany with Company of Snakes followed with new keyboardist Dean Rees. But Ridley fell ill late in 2002 and the band split up.
