During his 70-year career, the senior Conaway designed and built some of the earliest processing plants for Allen Family Foods, Frank Perdue and Preston Townsend, all of which are still operating today.
The pair found they had a dynamic spark of creativity between them, and sought out work on original compositions that would be pitched to TV and movie projects.
When ABC slated the new Miller/Boyett project to premiere on Tuesdays in March 1986, following some cast changes, it went into official production under the new title, Perfect Strangers.
Frederick and Salvay penned their first TV title track, "Nothing's Gonna Stop Me Now", for the series, which obliquely told the ballad of the show's two leads—Balki Bartokomous (Bronson Pinchot) and Larry Appleton (Mark Linn-Baker)--as the former had dreams of making it in America from the island of Mypos, while the latter had aspirations to make it in Chicago, after moving from Wisconsin.
Perfect Strangers went on to become a hit, running eight seasons on ABC, and made Frederick and Salvay's songwriting weekly staples in millions of households across the country.
Beginning in the 1986-87 season, Frederick and Salvay were asked to score selected episodes of NBC's Miller/Boyett-produced sitcom Valerie, which had premiered in March 1986, three weeks before the debut of Perfect Strangers on ABC.
Frederick and Salvay scored three episodes: one which aired in November 1986, another in April 1987 (which they co-scored with Steven Chesne) and a third in the spring of 1988, after the series had been retitled Valerie's Family.
Full House initially struggled in the ratings, but when ABC scheduled it on Tuesdays in addition to its regular Friday slot for a time in 1988, it began a gradual increase in audience size.
Frederick and Salvay's underscores for Full House, which were more sentimental and instrument-heavy than on earlier hit Perfect Strangers, became the signature sound the two are also most recognized for.
Once the format was revised and the original pilot set to shoot, Stamos's character became Jesse Cochran (later renamed Jesse Katsopolis as a nod to Stamos's Greek ethnicity), the super-cool rock musician brother-in-law of Danny Tanner (played in the unaired pilot by John Posey, before Bob Saget became available for the role).
However, series creator Jeff Franklin has stated that when the character was being renamed, he was reminded of Elvis Presley's twin brother Jesse, who had died at a young age.
Joining ABC's established Miller/Boyett shows on the newly developed TGIF in September 1989 was Family Matters, a spin-off from Perfect Strangers.
The closing theme that Frederick and Salvay wrote and recorded was a melody loosely based on "What A Wonderful World", featuring a more uptempo beat dominated by saxophone and culminating in an orchestral crescendo.
Frederick and Salvay wrote an original title track featuring a jazzy, ragtime piano prologue leading into an upbeat melody, again using high orchestration.
Family Matters was only a moderate success until Jaleel White's Steve Urkel was added in early 1990, becoming the show's breakout character.
It wasn't until the start of the series' fifth season in 1993 that Frederick and Salvay composed a closing version of "As Days Go By"; it was a hip-hop sounding rendition with a saxophone domination.
Frederick and Salvay composed all music for Going Places, but for the first time since Perfect Strangers, had another singer, Mark Lennon, perform the theme.
The Hogan Family was the only Miller/Boyett series from the Lorimar era to have not utilized Frederick and Salvay for most of its run, aside from the selected episodes they scored in 1986-88.
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.
The series' theme, one in a long line of feel-good, inspirational tunes from Frederick and Salvay, was performed by Joe Turano.
In the later years of their run with Miller/Boyett, Frederick and Salvay would alternate score composing duties with other resident talents such as Steven Chesne and Gary Boren.
Meego, which aired on the network's new "Block Party" lineup (a TGIF clone), was a departure from the usual production and musical styles of both Miller/Boyett and Frederick and Salvay.
Frederick and Salvay continued working for their longtime employers, even as their parent production companies went through further changes in the late 1990s.
In 1986, he and Salvay wrote the theme song to the short-lived CBS sitcom Better Days, a Lorimar series from producers Jeff Freilich, Stuart Sheslow and Arthur Silver.
Later, they wrote a more saccharine-tinged theme for the just-as-short-lived spring 1988 ABC comedy Family Man (no relation to the similarly titled Miller-Boyett series of two years later), which Frederick also performed.
In 1992, Frederick and Salvay were asked by Full House creator Jeff Franklin to handle scoring duties, with Gary Boren, on his new ABC sitcom Hangin' With Mr. Cooper.
