Sounds great! But the song Oh what a beautiful mornin is that what marc davis had in mine for the ride ? And noski when you say original music do you mean buddy baker had a original music score?If not the case why not Home on the range i think it fitz better.
Yes, Buddy Baker did write the music for Grim Grinning Ghosts and most of the cues are based on that, with the exception of the Attic, which is a minor/dissonent version of "Here Comes the Bride" (DLR and WDW versions, probably TDL too). In Phantom Manor, it may be harder to tell, but all the music except the stretching room is based on GGG also. Its just been put in 3/4 time.
As for your suggestion on the music, "Home on the Range" works too.
Yes, and to get my answer I went to the Widen your World site ,And (GUESS WHAT) Buddy Baker the Mastermind behind countless disney film scores and park tracks (including if you had wings ) reportedly began writing theme music for the attraction in a variety of different styles such as an introductory ballad, a double-time saoon style and an Epic Western style evocative of films like the big country and the magnificent seven.
