Main Street Music Loops


New Member
Hello everyone! I have some questions...
Ive seen in some internet links that there are 2 versions of the Disneyland (Anaheim) Main Street Music Loop.

1.-Main Street Music Loop (1972-1992)
2.-Main Street Loop (1992-Present)

And is there only ONE version of the Christmas Loop?
1.-Main Street Christmas Loop (1972-Present?)

Thank you so much for your help!
