In 1962, the American folk trio the Rooftop Singers recorded a version of the song. Group member Erik Darling recruited two friends to record a folk version of "Walk Right In" after hearing the original Cannon recording. Darling wanted the record to have a distinctive sound, so he and group member Bill Svanoe both played twelve string guitars on the song, although they had some difficulty in acquiring the instruments. Darling is quoted as saying that prior to the making of this record, "you couldn't buy a 12-string guitar... I ordered one from the Gibson Company, but in order to record [the song] with two 12-strings, we had to wait for the company to build a second one for Bill!" (a left-handed model).[2] The success of the song was a boon to Cannon, who was in his late 70s and had been forced to pawn his banjo the previous winter to pay his heating bill; he received royalties as a songwriter and saw renewed interest in his music, which led to a recording contract of his own.[3]
When released as a single, it spent two weeks at number one on the Billboard Hot 100 chart in early 1963.[3] It spent five weeks atop the Easy Listening chart, which later became known as the Adult Contemporary chart.[2] In addition, "Walk Right In" reached both the R&B chart (peaking at number four) as well as the country music chart, peaking at number 23.[2] The song reached number one in Australia on the Kent Music Report in 1963, and it made the Top 10 on the UK Singles Chart in the United Kingdom, peaking at number 10.[4] The song was included on the album Walk Right In, and was nominated for a Grammy Award in the category Best Folk Recording.
The French singer, author and composer Claude François (known to have become popular mostly by covering American and British hits in French) became famous on his debut, thanks to this song that he sang in French as "Marche tout droit". He had recorded previously, but had seemed doomed to never become famous. "Marche tout droit" was an important step for him on the path to success, which included composing the song, "Comme d'habitude", later world-famous as "My Way".
