Re: thread title—I understand the (potential) annoyance ~ haven’t read the whole ‘07 > present thread. BUT, given music’s powerful mnemonic tentacles, it’s a grand way to teach/learn vocabulary in ASL or British Sign Language. While some lyrics are a challenge to the interpreter, other songs flow beautifully organically. Many folk appreciate the “choreography” of a well-executed interpretation. It is a specialized type of Sign Language interpreting—excuse the slight thread drift. My only suggestion: if you do use more than a “gesture” or two, try to find the ASL   Cajoling works better than coercion for audience participation:)
