4th Performance - Delilah - "Flash Dance, What a Feeling" By Irene Cara - Sing Off - Series 3

It looks like delilah is having a see-saw performance week by week...with them not being consistent with their performances, i have a feeling they'll reach only the top 4 or even 5 if they mess up once to groups that are improving..this wasn't bad but i think because we're so used to amy being the powerhouse singer that we sometimes don't see how good they really are. she's a great singer but i'm not sure about it with this song however..B-
