It is most notable as the first US album to include three hard to find Who singles. The 1971 UK single "Let's See Action" was not released in the US, and for this album the title was changed to "(Nothing Is Everything) Let's See Action". Two other singles, "Join Together" and "Relay", were released both in the UK and US in 1972. US releases of "Relay" were re-titled "The Relay". The version of the song on this album was edited by use of a fade that occurs about 25 seconds early. "5:15" is the single version from the Quadrophenia soundtrack released in 1979, not the original single version released in 1973.
