Under the Influence is the twenty-third studio album by English rock band Status Quo, released in 1999.

The original Australian edition included "Sea Cruise" and "Pictures of Matchstick Men 1999".

[1] The 2006 Eurotrend budget label reissue ("Influence of Matchstick Men") includes "Pictures of Matchstick Men",[2] while the Dutch reissue from the same year also adds "Sea Cruise" and "I Knew the Bride".

[3] "Twenty Wild Horses" (Live) was included on the 2011 Fourth Chord/earmusic remaster (with the originally intended "bent fork" cover artwork), which also has "Sea Cruise" and "I Knew the Bride", but not "Pictures of Matchstick Men".

[4] Finally, the 2017 Edsel Records[5] and 2021 earmusic[6] reissues (which revert to the original "pub sign" cover), have all four bonus tracks.
