The band's potential was commented on by former Sounds magazine staff writer and later successful publicist Barbara Charone who stated that “Roger Chapman, Charlie Whitney, and Bobby Tench have been one step away from the big time for so long now that it makes you wonder what the problem is.

Chapman and Whitney signed to the Reprise label in 1973 and recorded Chapman Whitney Streetwalkers (1974) with a lineup including other members of Family (co-founder Ric Grech on bass, former bassists John Wetton and Jim Cregan providing bass and backing vocals respectively) and King Crimson (Wetton, plus saxophonist Mel Collins, drummers Ian Wallace and Michael Giles).

When writing about the album for Allmusic, Patrick Little commented:The mixture of rockers and ballads was not Family; yet there was added depth to the music, stemming from the evolved songwriting and from the involvement of so many musicians.

"Systematic Stealth" a lovely textured ballad and the slunky "Creature Feature" demonstrate the range of Roger Chapman's unusual voice, from gravelly crooning to just plain gravel.

[12] On 19 April the same year, they made their final appearance on Rockpalast, with a line-up which included Chapman, Whitney, Tench, keyboardist Brian Johnston, bassist Mickey Feat and drummer David Dowle who later joined Whitesnake.

Streetwalkers Live (1977) was their final album and included a rough and ready compilation of poorly recorded tracks, probably released to comply with contractual obligations.
