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[dubious– discuss], 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.
