ダ・ヴィンチ (Unknown Alternate ver.) - 水曜日のカンパネラ / Da Vinci (Alternate ver.) WEDNESDAY CAMPANELLA

This song is not mine. All rights go to author.
I found this on my hard drive and thought this was the regular version that came with the album, but apparently not..? Anyways, I have no clue what the name of this version is and I can't seem to find it on the internet aside from this 256 AAC that I managed to have. If anyone has the name please put it in the comments! Much appreciated!

i don't have the answers to your questions but thank you for uploading! hopefully you can figure out where this is from eventually, it's really interesting to hear :) maybe it's from a demo cd?
