Dan Sullivan - split to two people

This record contains credits for two different people. One is an operatic bass/baritone principally credited as Daniel Sullivan, but also known as Dan Sullivan and Dan O'Sullivan (in his sole Broadway appearance in The Most Happy Fella). He also has another credit here in the database as Daniel Sullivan, which needs to be combined.

The other is a reed player Dan Sullivan who has appeared in a number of Broadway orchestras in the 2010s.

Because it's a popular name, it's worth mentioning the more famous Daniel J. Sullivan, who has had a long career on Broadway and elsewhere as a director of plays. He appears in the database here with his middle initial for sake of disambiguation, but more accurately should be credited as "Daniel Sullivan".

And there's also Daniel D. Sullivan, an architect who while in college at M.I.T. performed on the cast recording of the 1951 Tech Show. His credit on the album is as "Dan Sullivan".

I've gone through and revised Dan Sullivan, Daniel Sullivan, and . I think they are appropriately grouped now, but I'm sure someone will let me know if they are not.
