Toronto folk-rock group Bobby Kris & The Imperials released a fairly straight-ahead cover version late 1965. The track became a major hit in Canada, reaching #8 in early 1966, but "Walk On By" was to be the band's only hit.
Funk/soul musician Isaac Hayes released a cover version in 1969 on his album Hot Buttered Soul and transformed the song into a twelve-and-a-half minute funk vamp. Edited for single release down to under 5 minutes, this single reached #30 on the U.S. charts.
The Average White Band cut a lightly disco-tinged version of "Walk On By" (featuring reggae and funk underpinnings) that charted in 1979. Though AWB is primarily remembered as an instrumental band, their version of "Walk On By" was a vocal track—as were many of their other songs.
In 1983, Australian act Jo Jo Zep covered the song in a slow, moody version that featured electronics and synthesizers. The track was a minor hit in Australia, peaking at #55, but was a major hit in New Zealand, hitting #6.
"Walk on By" was the first single from Cyndi Lauper's 2003 covers album, At Last. It was also included on Lauper's 2004 DVD Live at Last. It was released as a promo only. Remixes of the song reached #10 on the U.S. dance chart.
Kiki Dee recorded a version of the song in 1969 for Motown Records during her work on the Great Expectations album, but the song was not released until 2005 on the retrospective album Kiki Dee - Love Makes The World Go Round: The Motown Collection
