<Dd> We're gonna leave all your troubles behind </Dd> <Dd> keep on walkin' and don't look back . </Dd> <P> Smokey Robinson, the song's producer, specifically assigned Paul Williams to sing lead on the song . Although Williams had been the group's original lead singer during its formative years, his role had by 1965 been eclipsed by David Ruffin and Eddie Kendricks, who had both sung lead on Temptations hit singles . As such, Williams was often overlooked for leads, even on album tracks and B - sides, prompting him to complain, "shit, y'know, I can sing too!" </P> <P> "Don't Look Back" was originally this single's A-side, but was passed over by the nation's DJs in favor of the Ruffin - led "My Baby", which had a much bigger pop success than this song, and placed on the B - side . The song nevertheless was promoted as if it were an A-side and would the only B - side to chart on the Billboard Hot 100 for the group (but missed the Top 40 as it peaked at #83). </P>
