Trouble which got a nice response. Now
Wish You Were Here. She's playing a soft synth line you can't hear on videos. Very slow, downbeat way to start I must say.
Since everyone was having different opinions of the quality of their voices, here's Trouble where I think he sounds great. She seems like she's not being given enough to do here but watch him, though in person it did *seem* to sound like she was playing a very soft synth line accompaniment.
Wish You Were Here.... the vocals are bit wobbly, and you can kinda barely hear her synthesizer part:
