i was listening to the radio today, and they had an interview with her dad which is also her manager, and he said something like "well, Ashley developed acid reflux, and the acid burned her vocal chords, making her singing sound like a frog. now I told her she's not going to sing on SNL like a frog, so i wanted to use a recorded track. Ashley didn't want to do that, wanted to be herself.. or something, but i told her no and that was that. our new drummer was so excited about playing on SNL that he forgot to skip to a new track and instead started playing the song that had already been performed that night. Ashley was upset and stood on stage waiting for a comercial, but it didn't come so she just walked off"
that's pretty much what his excuse was
