Wagoner... now Goulet... Who will be the third?

We let it slide with Joey Bishop, Theresa Brewer and Deborah Kerr, and more recently with Peg Bracken, Judy Mazel and G.A. Renner, but they really do Die in Threes. And interesting, the New York Times obit headlines Bob Goulet as an "actor." The LA Times calls him a "singer."
