That first disco lady singer was absolutely awful. She was so off key and that dancing around....oy! The second one sounded great, but she kept singing to Simon and that was just bad.
I really did like the dance number that Paula choreographed. I don't usually like the group numbers. They are usually just boring, but last night's was very good.
I think Allison is really great, but just doesn't have the ability (yet) to redo an entire song like the other artists can, mostly because she's just young. I think she is one extremely talented girl, though.
