The show featured the group performing hits from the 1950s and 1960s along with comedy skits along the shows nostalgic theme but with a modern day twist, with performances from that era's well-known acts as well as popular acts of the 1970s.
Among the supporting members featured in the series were: Avery Schreiber, Kenneth Mars and Phillp Roth (All of them in the first season); Pamela Myers and actress Jane Dulo (she played the crabby Lady in the Window, who watched over the street scenes from the window of her apartment with undisguised disdain) (Both throughout the show's run), June Gable and Soupy Sales (Seasons 2 to 4); Michael Sklar (Season 2); and Karen Hartman (Season 4).
Interestingly, most of the stations that aired the show were ABC affiliates (like WISN-TV/Milwaukee), who would schedule it on Tuesday nights before the network's primetime lineup, which kicked off with Happy Days and Laverne & Shirley, two shows set in the late 1950s/early 1960s period that was also part of the act's routine.
