<Li> Tisha Campbell - Martin </Li> <Li> Vanessa Bell Calloway </Li> <P> The show's theme song "Living One on One", was written and performed by Shanice (wife of the series star Flex Alexander) and Tonex with music composed by Jonathan Wolff and Becky Kneubuhl (who composed the scene - change music for the first season). The theme song was slightly shortened and remixed by Detail and Ray J for the show's fifth season . A truncated version of the theme stripped of all lyrics except the words "One on One", was used as a closing theme, heard only in syndicated airings . </P> <P> The opening titles for the first three seasons featured the cast playing basketball on an outdoor court (though it also showed some characters doing other things at that same setting, e.g., Spirit checking out a boy who walks past her, and Arnaz playing the guitar only to be interrupted by a basketball bouncing in his direction that fell out of Duane's hand and he chases him). The fourth - season opening titles featured the cast in a dressing room getting ready for a night on the town, the end of the sequence featured a pan shot of the cast wearing different outfits in the mirror from what they are wearing in the beginning of the pan shot . The opening sequences for the first four seasons included a closeup shot of Flex, Breanna, and Arnaz before cutting back to a shot of the entire cast . The final season's opening titles featured the main cast (Breanna, Arnaz, and new characters D - Mack, Sara, Cash, and Lisa) at various places at the Venice Beach Boardwalk, before meeting back at the beach house to take a picture together . </P>
