From the wiki: “Barbara Mason, a soul / R&B singer from Philadelphia, Pennsylvania, had released a few singles while she was a teenager in the mid-1960s. ‘Yes, I’m Ready’ became Mason’s first big hit on the music charts, peaking at #2 on the Billboard R&B chart and #5 on the Billboard Hot 100 chart in the summer of 1965. While Mason would continue recording into the 1980s, this song has been her highest charting hit. Mason later re-recorded the song for her 1973 album, Give Me Your Love.
“Teri DeSario, a vocalist from Miami, Florida, was a high school classmate of ‘K.C.’ Casey, best known as the lead vocalist and songwriter for K.C. and the Sunshine Band. Casey liked the original recording and wanted to record a cover version of the song, and he was producing DeSario’s second studio album, Moonlight Madness, for Casablanca Records. Neil Bogart, president of the record label, had an idea to record the song as a duet, and it was the first single released from the album in late 1979. Their version of the song spent two weeks at #2 on the Billboard Hot 100 chart in March 1980, kept from the summit by ‘Crazy Little Thing Called Love’ by Queen. It also spent two weeks at #1 on the Billboard adult contemporary chart.
“‘Yes, I’m Ready’ was also recorded in 1987 as a duet by the artist Jed and American singer La Toya Jackson, but released only in Japan as a 7″ single where it failed to chart. The song was promoted by a series of interviews and two ‘live’ (lip-synced) performances on Japanese TV. (The video below links to one of those performances.) Most people don’t know this promo ever took place.”
