What is Ayu saying in her concerts at the start of the Encore part?

[nEwly]

When Ayu has finished the main part of a show and she starts with the encore part, she always talks with Yoshio and sometimes with other band mambers? What they are talking about?

And I have nother question:
When Ayu says every name of the dancers and the band manbers, she says always the same at the end, the last word. Is it "And at least AYU-CHAN?" or what is she saying? Does anybody know it?
