I got an email "officially" inviting me to the dance call? Whatever that means?

I actually got it on Friday? Can't tell if this is a callback of sorts  or just fun?

Public Service Announcement: Don't be fooled into thinking that just because it's a callback, you won't be asked to sing yet another song from your book, or be asked for yet another headshot and resume! (I know that it's in the "good little actor handbook" to always have those things with you, but sometimes  you don't get expressly told to bring those things to a callback, and it's easy to allow yourself to believe that because it's a callback, you don't particularly need them. I've seen a few people get burned at LOW by this exact scenario...)

Echoing what appj001 said up there, LOW is a little different in how they do callbacks... invited/asked to come to a dance call is NOT a callback, nor is not getting called for dance a rejection.  They will start doing invited callbacks at the end of dance calls being wrapped up. 

This afternoon I know callback emails went out for some roles in Fiddler and Merry Widow.

Motel, Perchik, Fiddler, Constable, Fyedka

Awesome. My dance call was cancelled for last Tuesday and rescheduled, did Anyone go on Wednesday and know what it's like.

I also heard of a Motel callback and a "Husband" in The Merry Widow...

More callbacks when out for some of the guys for Damn Yankees

Or any news on female callbacks for Damn Yankees (Lola)?

They had callbacks for women in Fiddler last week.

Do we think there will be more callbacks after tonight's dance call or are they essentially all out already
