Over the numerous releases of the "Canned Heat" single, two B-sides exist. "Wolf in Sheep's Clothing" is a funky instrumental that features an intro of two drum beats that lasts about 1.5 seconds and then enters a strongly bass-driven, repetitive melody (which is very reminiscent of "
Stayin' Alive" by the
Bee Gees). Many keyboard effects are used throughout the song's 4-minute duration. The song enters a percussion section at 3:07 and lasts for the remainder of the song, slowly fading out from 3:45. The song was originally released as part of the charity album
No Boundaries: A Benefit for the Kosovar Refugees in 1998 before being included on this single. It is also available on some editions of the
Synkronized album, the Australian double disc release being an example. The Chillington mix of "
Deeper Underground" is included on the second release of "Canned Heat". Chillington is not the name of an artist or DJ but instead the name of the studios at Jay's Home in Buckinghamshire. The Chillington mix heavily samples the Jamiroquai song "Getinfunky", which is found on some special releases of
Synkronized, including the Japanese release, where it replaced "Deeper Underground" as the bonus track, and alongside "Wolf in Sheep's Clothing" on the Australian double disc. On the
High Times: The Singles DVD, Jay comments on a bonus feature that the original
Godzilla song was just made of "
Ominous noises" which strongly matches the sound of "Getinfunky". When the song's "ominous noises" are pared away, it strongly suggests that "Getinfunky" is an early version of the
Godzilla song which later evolved into "Deeper Underground". ==Critical reception==
