Goldsmith never did a song score until... he was slated to do one with Paul Williams for "Picasso at the Lapin Agile". He died before doing it, I think. Or did he do one I don't know about?
Korngold, if you don't count operas, didn't do one (I don't think) until he had 3 songs in GIVE US THIS NIGHT (with O. Hammerstein). Or were they created after-the-fact?
Yes, Alice's Adventures in Wonderland was Barry's first. His second--that he completed--was Svengali, a TV movie where JB and Black wrote several songs for Jodie Foster to sing.
In between were a couple of projects with strange histories that didn't materialize: Ruggles of Red Gap--mid seventies, Barry and Black with Peter Sellers to star. Wonderful anecdote about this in the book about Don Black--Wrestling with Elephants.
Gulliver's Travels--same era, also Barry/Black. Financing ran out, production shut down, Barry withdrew his music. When the production resumed, Barry had moved on. Michel Legrand scored.

"Svengali, Jodie Foster, John Barry" - so disparate it sounds like a dragon53 post.
