Passage: After the album was released in early 1970, it seemed that the Bee Gees were finished. The leadoff single, "Don't Forget to Remember," was a big hit in the UK, reaching No. 2, but a disappointment in the US, only reaching No. 73. The next two singles, "I.O.I.O." and "If I Only Had My Mind on Something Else" barely scraped the charts. On 1 December 1969, Barry and Maurice parted ways professionally.Maurice started to record his first solo album, The Loner, which was not released. Meanwhile, he released the single "Railroad" and starred in the West End musical, Sing a Rude Song. In February 1970, Barry recorded a solo album which never saw official release either, although "I'll Kiss Your Memory" was released as a single backed by "This Time" without much interest. Meanwhile, Robin saw success in Europe with his No. 2 hit "Saved by the Bell" and the album Robin's Reign.
