"Disco King" earned a lot of airplay for Spencer Tracy, with the Triple M network adding "Disco King" to official rotation in Sydney, Melbourne and Brisbane, NOVA Sydney & Melbourne running the track in the high rotation Buzz bin for two consecutive weeks and NOVA 937 in Perth giving solid airplay over a six-week period. The video clip to "Disco King" also received rotation on Channel V, MTV and Rage.[3] The song created interest in the band from Interscope Records in the US.
"Cathy Hendrix in my office listens to triple j on the net all of the time and we just loved that song "Disco King". A musician friend saw Spencer Tracy playing a show in Melbourne and sent us a copy of their CD. When we put it on we were blown away -we just couldn't turn it off for a whole week." - Mike Dixon – USA manager (Ron Sexsmith)[4]
The song is described by reviewers as having "squelch-pop warmth and bouncy rhythms",[5] and being "almost contemporary Britpop in feel."[6]
