I saw a 35mm print of "Puppy Love" at Film Forum a few years back, and there was NO music over the title cards. I guess the original music must be lost.
Also, as for "Ye Olden Days", I heard the original title music on the colorized version seen on the "Robon Hood" Gold Collection DVD, but subsequent DVDs of the movie use the print from the Disney Treasures set with similar organ music. Even the Blu-ray, which has original titles, use the or organ music.
