 He had a particularly close friendship and relationship with the late Beverly Sills and was also a close friend and adviser to Plácido Domingo in addition to being his publicist.
 Vincent also worked for Mikhail Baryshnikov and a handful of musicians other than opera singers, including conductors Erich Leinsdorf, Leopold Stokowski and Georg Solti; the cellist Mstislav Rostropovich; and the violinist Isaac Stern.
 He also worked frequently with his colleague, fellow publicist Margaret Carson.
