I too got an recall audition email within the promised 48 hours, it was 24 hours actually!
Mine is next Thursday, again as others have said on here I wish I knew what role specific I was auditioning for!
Having been to the first audition and had a fabulous fun time with all the feel good energy and enthusiasm of everyone there, I cant wait to find out what the 2nd audition is like. I never said I had any specific skills so it will be very interesting to see what they think I can do!
good luck everyone!
