"It Ain't Over 'til It's Over" is a song recorded, written, and produced by American musician Lenny Kravitz for his second studio album, Mama Said (1991). Released as the album's second single in June 1991, the song is a mid-tempoballad, musically inspired by Motown, Philly soul, and Earth, Wind & Fire. The horn line at the end is actually performed by the Phenix Horns from Earth, Wind & Fire. "That song just came out one day, and I knew it had a classic vibe. And I still love that song very much today", Kravitz said in an interview for VivaMusic.com in 2000. The line is based on a Yogiism, or quotation from Yogi Berra: "It ain't over 'til it's over." It was his first Top 10 on the Billboard Hot 100 of his career, and his highest peak in the chart.
The music video, directed by Jesse Dylan, features Kravitz and his band performing the song. It also featured a violin section, which performs the main song riff. In the studio, Kravitz actually plays all the instruments, apart from the string and horn sections. Different kinds of background lighting colors were featured in the video.
