One Night Only is a live album by rock band Thin Lizzy, released in 2000. Thin Lizzy had reformed in 1994 for a series of gigs marking ten years since the band split in 1984. Latter-day Lizzy guitarist John Sykes now took the lead vocal while Marco Mendoza was recruited on bass. The venture was popular enough to be repeated but by the time this album came out, original drummer Brian Downey had decided the affair was too disorganised [citation needed] and retired from the group leaving none of the original trio remaining. Keyboardist Darren Wharton also quit around the time of this album's release. The band, led by Sykes and Scott Gorham, subsequently continued performing with various lineups. This album features ex-Ozzy, Whitesnake, and Black Oak Arkansas drummer Tommy Aldridge.
