Black Russian had some assistance with the lyrics, perhaps because English is not their native language; they hardly spoke the language at all at the time that they defected.  Lyricists who lent a hand include Allee Willis, who co-wrote the lyrics for their beautiful first single “Leave Me Now”.  Willis has had a long career as a writer, songwriter, set designer, and artist.  From Wikipedia:  “[Allee Willis]’ songs have sold over 50,000,000 records, including ‘September’ and ‘Boogie Wonderland’ by Earth, Wind and Fire, ‘Neutron Dance’ by the Pointer Sisters, ‘What Have I Done to Deserve This?’ by Pet Shop Boys with Dusty Springfield, and ‘Lead Me On’ by Maxine Nightingale.  Willis has collaborated with hundreds of leading artists and composers from all fields of music, including Bob Dylan, Patti LaBelle, James Brown, Herbie Hancock, Deniece Williams, and Motown legend Lamont Dozier.”
