Advent responsary

[musicus]

Can anyone point me to an online source for Aspiciens a longe, the Matins responsary for the first Sunday of Advent? There are plenty of recordings of it, but I am after the chant notation.

Alternatively, perhaps someone who has it could PM me with a scan? It doesn't have to be tidy, because I will reset it.

Thank you.
