In 1997, Tommy Aldridge filled in on drums when Brian Downey was unable to, and became a full member when Downey left shortly thereafter. This line-up remained stable through to 2000, when the group recorded a live album, "One Night Only". The band went on to tour the US playing clubs in early 2001, but Wharton had already left the band by the time of the tour. From 2000 to 2003, Mendoza toured with Ted Nugent, and with Whitesnake in 2004. Sykes released two solo albums during 2002–03, while Gorham worked with his band 21 Guns. Thin Lizzy performed sporadically during this period, recruiting some musicians for single tours, such as bass guitarist Guy Pratt for the Global Chaos Tour of 2003.
