Stone was influential in guiding KSOL-AM into soul music and started calling the station K-SOUL. The second was a popular soul music station (sans the K-SOUL moniker), at 107.7 FM (now known as KSAN). The current KSOL has a different format and is unrelated to the previous two stations. While still providing "music for your mind, body, and your soul" on KSOL, Sly Stone played keyboard for dozens of major performers including Dionne Warwick, Righteous Brothers, Ronettes, Bobby Freeman, George & Teddy, Freddy Cannon, Marvin Gaye, Dick & Dee Dee, Jan & Dean, Gene Chandler, and many more, including at least one of the three Twist Party concerts by then chart topper Chubby Checker held at the Cow Palace in San Francisco in 1962 and 1963. The concerts were put together by "Big Daddy" Tom Donohue and Bobby Mitchell from the then infamous KYA 1260 AM radio station and largely choreographed by Jerry Marcellino and Mel Larson who went on to produce many Motown artists including Michael Jackson, Diana Ross, and some of the top artists of the day.
