so, old timey musicians sit down and their audiences stand up and dance?
and blue grass bands stand up and their audiences sit down?

In fiddle contests, most of the tunes will be "old-timey" music,
in fact the names of the organzations that produce the contests
often have the word old time in their name,such as,
California State Old Time Fiddlers Association.

I think of old time being mainly instrumental,
and blue grass has vocals.

they both are great!
