After the popularity of disco waned, so did album sales for the Bee Gees — widely considered standard bearers for genre. “… And yet Bee Gees songs still hit huge in the US (in the early 1980s); they just did it without the words ‘Bee Gees’ on the record cover,” (Stereogum). “Consider Barbra Streisand’s 1980 LP Guilty. Barry Gibb produced the album with his regular Bee Gees collaborators Karl Richardson and Albhy Galuten. Gibb also wrote or co-wrote every song on the LP. He sang, played guitar, and did the horn and string arrangements on Guilty. Guilty was basically a Bee Gees album, except with Barbra Streisand singing lead … On Guilty, the ballads dominate. ‘Woman in Love,’ the biggest hit from Guilty, is an extremely Bee Gees song, and yet nobody would confuse it with disco.
… Multi-tracking his own voice, Barry Gibb does the backing vocals, echoing the song’s central melody and anchoring it so that Streisand can sing all her showiest runs. Gibb and Streisand recorded the song in Miami with an elite squad of session musicians, and it sounds lush and clean and expensive. Strings and horns hum to each other. Electric pianos glow. The heavily processed guitars murmur fancily. On the chorus, the echo on Gibb’s voice is immaculate, and Streisand holds notes for absurd lengths of time. It’s terribly dramatic, in a good way. ‘Woman in Love’ (was) Streisand’s fifth and final #1 hit.”
After a few verses and choruses in Eb minor, 3:03 brings a shift up to E major for a final chorus. Streisand’s famously strong belt takes top billing here, well above melody, lyric, arrangement, etc.!
