Predictable for Hannah, Tamera's could be awesome, Sam Bailey will excel with that (love that song also
), Rough Copy's could be interesting, we'll see about Sam C...probably one of the better choices for him given the options though. I don't think I know Luke's song (will look it up in a minute), Abi's will either be hit or miss and er Nicholas...well...I'm sure he'll sing it well I guess?
