I have been asked to start making videos of me signing parts of the Liturgy and hymns, so that my potential future students can watch them. They are on YouTube, if anyone else wants to make use of them. Please feel free to show them, share them, and request others. They are American Sign Language, without audio, with French captions.
The first video is of the French version of the “Common Doxology”:
The next video is of the Lord’s Prayer/Notre Père:
Hopefully these are useful to you, or at least interesting.
