<P> Programs that ensued for the duo included Step By Step in 1991 . The latter 's title track , `` Second Time Around '' , was sung by Frederick in a duet with Teresa James . It illustrated the story of the show 's newly married couple , Frank Lambert ( Patrick Duffy ) and Carol Foster ( Suzanne Somers ) , as they had visions of mixing their households of kids together . Step By Step was another TGIF hit , running six seasons on ABC and its seventh and final on CBS . From 1992 to 1994 , Frederick and Salvay 's newest project with Miller / Boyett was at first titled A New Day in its earliest development . Following a revamp in its creation ( by Bickley / Warren ) , it premiered on TGIF in March 1993 as Getting By . The series had two different theme songs during each of its two seasons , the second of which aired on NBC . The first theme that Frederick and Salvay wrote was sentimental in nature with woodwind instrumentation , and sung by Mark Lennon . The second theme had the funk / hip - hop sound that had started to be heard on sister shows such as Family Matters , and had a different male vocalist . In 1994 , the two worked on Miller / Boyett 's single - season comedy On Our Own . It starred Ralph Louis Harris and the six Smollett siblings as a family learning to fend for themselves after the death of their parents . The series ' theme , one in a long line of feel - good , inspirational tunes from Frederick and Salvay , was performed by Joe Turano . </P>
