<P> The show's theme music, "Kiss Me", was composed by Stu Gardner and Bill Cosby . Seven versions of this theme were used during the run of the series, making it one of the few television series to use multiple versions of the same theme song over the course of a series . For season four, the theme song music was performed by musician Bobby McFerrin . </P> <P> Due to legal complications regarding the background mural, the opening for season seven (filmed in August 1990) was replaced with the one from the previous season . The original season - seven opening, with slight modifications, returned to use in the beginning of season eight . </P> <Table> <Tr> <Th> Actor </Th> <Th> Character </Th> <Th_colspan="8"> Seasons </Th> </Tr> <Tr> <Th> </Th> <Th> </Th> <Th> </Th> <Th> </Th> <Th> 5 </Th> <Th> 6 </Th> <Th> 7 </Th> <Th> 8 </Th> </Tr> <Tr> <Td> Bill Cosby </Td> <Td> Dr. Heathcliff "Cliff" Huxtable </Td> <Td_colspan="8"> Main </Td> </Tr> <Tr> <Td> Phylicia Rashad </Td> <Td> Clair Olivia Hanks Huxtable </Td> <Td_colspan="8"> Main </Td> </Tr> <Tr> <Td> Lisa Bonet </Td> <Td> Denise Huxtable--Kendall </Td> <Td_colspan="3"> Main </Td> <Td_colspan="2"> Recurring </Td> <Td_colspan="2"> Main </Td> <Td> </Td> </Tr> <Tr> <Td> Malcolm - Jamal Warner </Td> <Td> Theodore "Theo" Huxtable </Td> <Td_colspan="8"> Main </Td> </Tr> <Tr> <Td> Tempestt Bledsoe </Td> <Td> Vanessa Huxtable </Td> <Td_colspan="8"> Main </Td> </Tr> <Tr> <Td> Keshia Knight Pulliam </Td> <Td> Rudith "Rudy" Lilian Huxtable </Td> <Td_colspan="8"> Main </Td> </Tr> <Tr> <Td> Sabrina Le Beauf </Td> <Td> Sondra Huxtable--Tibideaux </Td> <Td> Recurring </Td> <Td_colspan="7"> Main </Td> </Tr> <Tr> <Td> Geoffrey Owens </Td> <Td> Elvin Tibideaux </Td> <Td> </Td> <Td_colspan="2"> Recurring </Td> <Td_colspan="5"> Main </Td> </Tr> <Tr> <Td> Joseph C.
