1776 should not be in quotation marks at all because it is a title of a large work, so that solves one problem.

Which is your favorite song from
1776: "Is Anybody There?" "The Egg," or "Momma, Look Sharp"?
Actually, I hate the question mark in the first title throwing off my punctuation, so I'd switch them to "The Egg," "Momma, Look Sharp," and "Is Anybody There?" especially since the sentence is a question anyway.
