A version by boy band New Kids on the Block, slightly re-titled "Didn't I (Blow Your Mind)", was featured on the group's 1986 self-titled debut album. Their version was later released as a single in 1989 in an attempt to boost sales of its parent album in light of the group's subsequent success. The single peaked at number eight on both the US and UK pop charts, peaking in November 1989 in the US and in October of the following year in the UK (as a double A-side alongside "Let's Try It Again").
