I chose to count "The Song About Investing Tuppence In The Bank From Mary Poppins" as an acceptable approximation of the title; it was obvious you knew which song it was, and I don't know if I'd have been able to get the exact title from memory either.

With "Get Me To The Church On Time", I think I just assumed that if you knew the song, you knew where it was from, and updated the list accordingly.
