This song captures the joyful spirit of an impromptu celebration, written by Sam Cooke while on tour. The recording session itself mirrored the title, with friends invited and a very happy atmosphere, full of ad-libs and laughter. It was considered the "lighter" of two songs recorded that day, with an eighteen-piece backing group and additional backing vocals and handclaps adding to the festive mood. This feeling of shared joy and community became a hallmark of Cooke's live performances, often closing his shows with confetti and encouraging the audience to keep the party going. At its heart, "Having a Party" is an invitation to let loose and revel in the moment with loved ones.
