"Smoke on the Water" was included on "Machine Head", which was released in early 1972, but was not released as a single until a year later, in May 1973. ("Never Before" and "Highway Star" were the first singles issued from the album.) The band members have said that they did not expect the song to be a hit, but the single reached number 4 on the Billboard pop singles chart in the United States during the summer of 1973, number 2 on the Canadian RPM charts, and it propelled the album to the top 10 more than a year after its release. Live performances of the tune, featuring extended interplay between Blackmore's guitar and Jon Lord's Hammond organ, would become a centrepiece of Deep Purple's concerts, as in the live version found on the album "Made in Japan". Warner Brothers included the live version of "Smoke on the Water" from "Made in Japan" as the B-side of the "Smoke on the Water" studio single.
