Rundgren enhanced the Furs' sound by adding new elements to their musical arrangements – along with his own varied musical contributions, Rundgren brought in session musicians to augment the band. Gary Windo was a renowned saxophonist in the jazz world who had in recent years collaborated with major rock acts like Ian Hunter and Nick Mason. Extra horn work was contributed by Donn Adams, a longtime player with the American blues rock band NRBQ. A classical cellist, Ann Sheldon, was recruited from the Royal College of Music. Lastly, the seasoned pop backing vocal team of Flo & Eddie were called in by Rundgren to round out many of the songs. The instrumentalists had all been accepted by the band willingly, even enthusiastically – the backing vocalists, however, were another matter.
