Produced by Bob Gaudio, it was a double album of concert recordings which included the two studio recordings "[[Spend the Night in Love]]" and "Heaven Must Have Sent You (Here in the Night)" sung by Valli. The latter became a UK single but failed to chart, while the former was released as a single in America, inching its way into the [[Billboard Hot 100|Hot 100]] and became a top-5 hit, the group's last, in [[South Africa]].<ref>{{cite web|title=SA Charts 1965–March 1989|url=http://www.rock.co.za/files/springbok_top_20_(F).html|access-date=5 December 2018}}</ref> Valli had planned to add his daughter Francine to the act in 1980, but Francine unexpectedly died that year.<ref>{{Cite web |last= |date=May 26, 2008 |title=Frankie Valli Oh, What a Life! |url=https://people.com/archive/frankie-valli-oh-what-a-life-vol-69-no-20/ |access-date=2023-06-28 |website=[[People (magazine)|People]] |language=en}}</ref>

In 1984, a long-awaited collaboration between the Four Seasons and the Beach Boys, "East Meets West", was released on FBI Records, owned by the Four Seasons Partnership, which included most of the surviving Beach Boys (including Brian Wilson). However, the record did not sell well. Even after the rise and fall of the band's sales in the disco era, the Four Seasons, in one version or another, continued to be a popular touring act, with Valli and keyboardist/music director [[Robby Robinson (musician)|Robby Robinson]] (who joined in the early 1980s)<ref name="Eggers">{{cite web | last=Eggers | first=Kerry | title=Frankie Valli: a man for all seasons | website=Pamplin Media Group | date=20 June 2018 | url=https://pamplinmedia.com/pt/11-features/398839-293392-frankie-valli-a-man-for-all-seasons | access-date=2021-12-01|quote= Valli: Including four singers, we have 15 or 16 in our group. We have a couple of new members. I feel good about what we have now. It's something you put together very slowly to make sure you have the right people.

Although Gaudio is still officially part of the band (he and Valli are still equal partners in the Four Seasons Partnership), he now restricts his activities to writing, producing, brand management and the occasional studio work. In August 1985, MCA Records released the band album ''Streetfighter'', which yielded two singles in the title track and "Book of Love", a [[post-disco]]-style revamp of the Monotones' 1957 recording.  In September 1992, the band released an album entitled ''Hope + Glory'' on the MCA/Curb label; this is the most recent band studio album to date, but Valli has released three solo albums since then. (On at least one or two occasions, starting in the late 1980s or early 1990s, Long would make guest appearances with Valli and the band at select shows, but it is unclear if this included full performances or parts of concerts.)<ref name="Joe Long interview with Stuart Miller"></ref> Nick Massi also had occasional brief reunions with the group.<ref>{{Cite web |last=Waldo |first=Anetta |date=2023-10-29 |title=14 Surprising Facts About Nick Massi |url=https://facts.net/celebrity/14-surprising-facts-about-nick-massi/ |access-date=2024-06-03 |website=Facts.net |language=en-US}}</ref> In 1994, "December 1963 (Oh What A Night)" re-entered the Hot 100 by way of a remix.
