I'm pleased to say that I was able to clearly identify the Gibson Bathing Girl playing in the live recording

Without your information DavidG, that would have remained an "unknown" as I have been unable to find any recording of it at all.
It was written in 1907 so fits perfectly with Main Street. Thank you.
Just the other dozen to find now. I wonder how many more obscure tracks he recorded (that aren't on CDs). This is going to be a toughie I think.
Re Casey's, I seem to recall hearing Take me out to the ball game playing in there at one time but it certainly now shares at least four of the Gibson Girl tracks and in order. One I shall be checking this year. As a thought, I wonder if the player piano in there played a loop originally? I'm sure it appeared to in the early days (not live, of course, but a recording similar to the way Disney & Co worked with the organ). My wife and I recall (going back to the very early days of the park) that the music played in the back room but not in the serving area - in fact we remember looking for where the music was coming from and expected to see either a player piano or a live pianist playing in there. Can't think why we would go looking for the music if it was coming out of speakers above our heads? We found, of course, the player piano. Looking at videos on Youtube, the player piano seems to have been removed. It was just on the left as you entered the back room. Seems to be extra seats there now. Maybe they changed the loop when they removed it? Speculation I know but seems logical. Take the piano out to make extra room, remove the loop as it's no longer there, play the Gibson Girl loop as it's similar. Guess we may never know now. I'll check on the piano and see if it really has gone.
