...And Then There Were Three... is the ninth studio album by the British band Genesis and was released in 1978. It is the band's first album as a trio. The title ...And Then There Were Three... comes from a verse of the children's rhyme "Ten Little Indians" ("Four little Injuns up on a spree, One got fuddled and then there were three"); is a reference to the recent departure of Steve Hackett, reducing Genesis to a trio (which would result in their longest unchanged line-up, which lasted until 1996). The song "Scenes from a Night's Dream" is based on the adventures of comic strip character Little Nemo, and is the first Genesis song with lyrics written entirely by Phil Collins. "Say It's Alright Joe" is a torch song about a drunk who goes into a drunken stupor.
The album reached No.3 in the UK Albums Chart, and remained in the charts for 32 weeks having been bolstered by the UK Top 10 success of "Follow You Follow Me", which also became Genesis' first hit US single. ...And Then There Were Three... reached No.14 on the US chart, becoming their first Gold (eventually Platinum) album there (see RIAA certification).
While many of the songs were still progressive in terms of instrumentation and lyrics, the arrangements went from the more classical, movement-style composition of previous albums to the more standard verse/chorus/bridge format of popular songwriting. This was the final Genesis album to use a Mellotron, which is used on just one track, "Many Too Many".
A digitally remastered version was released on CD in 1994 on Virgin in Europe and Atlantic in the US and Canada. The booklet on the remaster features the lyrics although, the gatefold picture is missing. A SACD / DVD double disc set (including new 5.1 and Stereo mixes) was released on 2 April 2007. It was released as a CD / DVD double disc set in the US and Canada.
