The second single from Kershaw's debut solo album Human Racing, it was among his more popular singles spending three weeks at #4 in the UK charts and becoming a hit throughout Europe. It is also the song with which he is most closely associated in the U.S., where it narrowly missed going Top 40. Kershaw performed this song at Live Aid in London's Wembley Stadium, in July 1985.
Kershaw's prior single, his debut, had failed to be a major hit, and it was on the strength of this record's success that the earlier single, "I Won't Let the Sun Go Down on Me", was promoted for a re-release. This time the single went all the way to #2 in the UK, becoming his highest-charting single there to date.
"Wouldn't It Be Good" was released in a single version and an extended 12" version. The main synth tune was produced using a combination of PPG Wave 2.2 and a Yamaha DX7. A remix by Simon Boswell, clocking in at 7:20, appears on the album Retro:Active 4: Rare & Remixed.
