===1970–1979: Bee Gees comeback===
In August, the pair returned to the studio and they announced that the Bee Gees were back, with or without Barry's contribution. One of the fourteen songs, "Back Home" and "I'm Weeping" was also released on ''2 Years On''. On 21 August it was announced that Barry had rejoined the group and they were recording together. The first song after the announcement was "[[Lonely Days]]" which reached No. 3 in the [[US Billboard Hot 100]]. On the ''[[2 Years On]]'' album, Gibb's songs included "Alone Again". He also co-wrote and sang lead vocals on the title track as well as "Man For All Seasons". In December 1970, Gibb recorded a demo "After the Laughter".<ref name="demo">{{cite web |url=http://www.columbia.edu/~brennan/beegees/70.html |title=Gibb Songs: 1970 |last=Brennan |first=Joseph |website=Columbia.edu |access-date=21 May 2013 |archive-date=24 October 2012 |archive-url=https://web.archive.org/web/20121024101808/http://www.columbia.edu/~brennan/beegees/70.html |url-status=live }}</ref> The Bee Gees had their first US No. 1 single "[[How Can You Mend a Broken Heart]]", with Gibb contributing on the song, writing with Barry and singing lead vocals on its first verse.<ref>{{cite web |url=http://www.columbia.edu/~brennan/beegees/71.html |title=Gibb Songs: 1971 |last=Brennan |first=Joseph |website=Columbia.edu |access-date=12 July 2014 |archive-date=23 October 2018 |archive-url=https://web.archive.org/web/20181023000333/http://www.columbia.edu/~brennan/beegees/71.html |url-status=live }}</ref>

In April 1972, two months after the departure of drummer Geoff Bridgford, he wrote his last solo composition on a Bee Gees record until 1999, "Never Been Alone".<ref>{{cite web |url=http://www.columbia.edu/~brennan/beegees/72.html |title=Gibb Songs: 1972 |last=Brennan |first=Joseph |website=Columbia.edu |access-date=12 July 2014 |archive-date=10 January 2015 |archive-url=https://web.archive.org/web/20150110063907/http://www.columbia.edu/~brennan/beegees/72.html |url-status=live }}</ref> In 1976, on the group's ''[[Children of the World]]'' album, he sang lead on "[[Love Me (Bee Gees song)|Love Me]]" as well as doing [[falsetto]] on the track's coda, and he also used his falsetto on his lead vocal part on the song "Lovers" as Barry provided lead vocals on the entire song. On the ''[[Saturday Night Fever (soundtrack)|Saturday Night Fever]]'' soundtrack, he did not sing lead vocals on any Bee Gees song, unlike their previous and next albums. Four tracks off the album reached the UK Top 10; "How Deep Is Your Love", "More Than A Woman", "Stayin' Alive", and "You Should Be Dancing". Moreover, "Night Fever" spent longer at #1 than any track in 1978.<ref>{{cite web |last1=Breihan |first1=Tom |title=The Number Ones: The Bee Gees' "Night Fever" |url=https://www.stereogum.com/2066834/the-number-ones-the-bee-gees-night-fever/columns/the-number-ones/ |website=Stereogum |access-date=10 March 2023 |archive-url=https://web.archive.org/web/20230105054729/https://www.stereogum.com/2066834/the-number-ones-the-bee-gees-night-fever/columns/the-number-ones/ |archive-date=5 January 2023 |date=6 December 2019 |url-status=live}}</ref>
