Some callers insert the word 'Leads' (or 'Leaders') before calling
Right | Left Roll To A Wave when
they actually want everyone to do the call. This terminology is
confusing because both the Leaders and the Trailers have an
active part in the call. Also, this terminology is ambiguous from
formations in which the Leaders are Back-to-Back,
and the Trailers are Facing (e.g., Parallel Inverted Lines):
Does everyone do the call, or just the Leaders?
Our advice to callers is to avoid using the word 'Leads' (or 'Leaders')
unless only those dancers are to do the call.
