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.
